1 00:00:00,060 --> 00:00:05,460 So let us start building our application rate, so if you go to a boot support package, the recommended 2 00:00:05,460 --> 00:00:08,520 driver for any time HDMI CD, right? 3 00:00:08,520 --> 00:00:13,590 So that is the first driver file that giggling in our mean application, right? 4 00:00:13,590 --> 00:00:19,430 So I should include Dan Hicks tmr CD, right? 5 00:00:19,530 --> 00:00:19,700 Right. 6 00:00:20,370 --> 00:00:25,350 Then all the hardware login information will be in the experimental stage. 7 00:00:25,770 --> 00:00:31,050 OK, so this is the second driver file that the required rate, then we proceed to perform an initialization. 8 00:00:31,050 --> 00:00:35,070 So if you just explore the driver we have. 9 00:00:36,380 --> 00:00:41,630 Initialize function present in our code, right, so we will just be declaring the instant structure. 10 00:00:41,900 --> 00:00:43,520 OK, so let me just. 11 00:00:45,080 --> 00:00:50,690 Declare an instance structure will be naming this esteemed, right, then we declare the function which 12 00:00:50,690 --> 00:00:54,230 could be used to perform an initialization of a time or two. 13 00:00:54,530 --> 00:01:00,740 You just need this SDMI in it and then we proceed to call TMI initially today. 14 00:01:00,750 --> 00:01:05,870 So there's just requiring an instant structure and the device A.D. so we go ahead and return the state 15 00:01:05,870 --> 00:01:07,670 as wishes of indicating. 16 00:01:08,710 --> 00:01:10,840 Stewardess saying this would be close to. 17 00:01:11,880 --> 00:01:14,730 Initially, the first argument is an instance structure, right? 18 00:01:15,090 --> 00:01:15,930 So it will be. 19 00:01:17,460 --> 00:01:21,780 And then the second argument that we need to add is the device at any rate. 20 00:01:21,780 --> 00:01:27,600 So we need to explore the experimental fight and there we will be finding dmaa. 21 00:01:28,050 --> 00:01:28,270 Right. 22 00:01:28,370 --> 00:01:33,680 This will lead us to an instance where we have all the information related to the exciting work. 23 00:01:33,690 --> 00:01:35,980 So we'll just be copying this device. 24 00:01:36,330 --> 00:01:38,580 We go ahead and we add it to what you write. 25 00:01:38,970 --> 00:01:41,790 So this completes the process of initialization. 26 00:01:42,060 --> 00:01:45,780 Now we will be verifying whether initial edition is successful or not. 27 00:01:45,960 --> 00:01:46,200 No. 28 00:01:46,200 --> 00:01:51,510 In fact, our miniaturization will be to provide our application rate to. 29 00:01:51,510 --> 00:01:56,550 In that case, you could skip the process of verifying whether initial edition is successful. 30 00:01:57,390 --> 00:02:02,040 So let me just skip the process of checking whether initial is successful or not. 31 00:02:02,370 --> 00:02:06,420 And we will be proceeding to do a configuration of our time, right? 32 00:02:06,420 --> 00:02:06,720 So. 33 00:02:07,920 --> 00:02:13,050 Our first thing that we do with the timer is to forcefully stop it great, so we'll call a stop phone 34 00:02:13,050 --> 00:02:15,240 should this required an instant structure idea. 35 00:02:15,730 --> 00:02:16,220 Yeah, no. 36 00:02:16,230 --> 00:02:23,250 So in the case, when we are utilizing only a single timer there, that Yamashita number will be close 37 00:02:23,250 --> 00:02:24,030 to zero rate. 38 00:02:24,030 --> 00:02:27,120 So we'll be calling pmrc to stop with. 39 00:02:27,120 --> 00:02:32,430 The first argument will be the instance structure and second, when will be the EMI CTA number, which 40 00:02:32,430 --> 00:02:33,690 is seal, right? 41 00:02:34,230 --> 00:02:36,660 Then we will be performing. 42 00:02:37,170 --> 00:02:38,940 Then we will be setting up the mode right. 43 00:02:38,940 --> 00:02:42,480 So let's assume that we want to operate our timer in adult mode. 44 00:02:42,510 --> 00:02:45,000 OK, so first we'll be reading an existing option. 45 00:02:45,000 --> 00:02:50,160 So we have the function referred to as a gate option that will retain the existing option that we have 46 00:02:50,160 --> 00:02:51,850 in for any excitement. 47 00:02:52,140 --> 00:02:53,790 Again, this requires you that you do. 48 00:02:53,790 --> 00:02:55,590 So really just be calling this. 49 00:02:56,790 --> 00:02:57,720 OK, you really do. 50 00:02:58,110 --> 00:03:00,820 Let it just got a name, though, very well as option. 51 00:03:00,840 --> 00:03:02,130 OK, call this function. 52 00:03:02,490 --> 00:03:06,840 This required first argument as an instance structure and the TMI CGI number two. 53 00:03:06,840 --> 00:03:13,110 Once we have an existing option, we'll give, we'll be updating the option with an option that we want 54 00:03:13,110 --> 00:03:14,970 the same great option or with. 55 00:03:16,180 --> 00:03:22,020 Now, if you go ahead and look for the different options that we have over here, so we want to just 56 00:03:22,030 --> 00:03:23,440 operate the. 57 00:03:24,540 --> 00:03:29,100 Timer in and down, right, so we'll just be copying this don't count option, OK? 58 00:03:29,400 --> 00:03:31,050 And we'll be adding your door here. 59 00:03:31,130 --> 00:03:31,350 Right. 60 00:03:31,350 --> 00:03:34,710 So this will allow us to use our timer downward. 61 00:03:34,720 --> 00:03:36,720 So once we update our option variable. 62 00:03:37,050 --> 00:03:44,700 Now we call the second option function that help us to set the specific the user's specific option into 63 00:03:44,700 --> 00:03:45,810 the timer. 64 00:03:45,840 --> 00:03:47,100 So let's just call this. 65 00:03:47,850 --> 00:03:53,180 So this arbitrary argument first one is an instant structure of my CTA number and adoption that user 66 00:03:53,200 --> 00:03:54,030 want to say great. 67 00:03:54,480 --> 00:03:58,590 So first argument is an instant structure, which is Steber. 68 00:03:58,590 --> 00:04:04,500 The second argument is that the MCP a number and the last argument will be the option that we want the 69 00:04:04,500 --> 00:04:05,080 same right? 70 00:04:05,400 --> 00:04:06,000 So once we. 71 00:04:07,040 --> 00:04:12,800 Correctly set up with the option, we need to load our timer such that be able to calculate the timer 72 00:04:12,800 --> 00:04:17,810 function is consuming, and we will be assuming here that the delay that our function, which we are 73 00:04:17,810 --> 00:04:22,690 profiling will always consume the time less than 15 seconds. 74 00:04:22,970 --> 00:04:29,540 So this you need to make sure whenever you load your timer with the specific count that you load it 75 00:04:29,870 --> 00:04:30,530 with the value. 76 00:04:30,530 --> 00:04:38,540 So set it exceed the specific delay that you are expecting out of an application rate or a function 77 00:04:38,540 --> 00:04:39,480 that you are profiling. 78 00:04:39,500 --> 00:04:43,130 So here we have a set reset value function. 79 00:04:43,160 --> 00:04:48,910 OK, so this allows us to load our counter register to provide this specific right. 80 00:04:49,190 --> 00:04:53,000 So we go ahead and first declared a new 32 variable rate. 81 00:04:53,000 --> 00:04:56,000 So the way you do because this. 82 00:04:57,180 --> 00:05:04,200 Except the value in a utility to format, right, so we already know that we configure our timer to 83 00:05:04,200 --> 00:05:05,760 operate at 100 meters away. 84 00:05:05,760 --> 00:05:11,390 So if clock frequency that we have used is 100 meters, so you 32 count. 85 00:05:12,090 --> 00:05:18,870 OK, so first we need to add and then we got to adhere so to zero one two three one two three. 86 00:05:19,130 --> 00:05:20,370 So this is a hundred megahertz. 87 00:05:20,940 --> 00:05:26,440 Then to achieve a delay of 15 seconds, we just need to multiply by the factor of 50. 88 00:05:26,570 --> 00:05:26,730 Right. 89 00:05:26,730 --> 00:05:32,850 So we call the set reset value function, though it is required for us to document SDMI. 90 00:05:33,210 --> 00:05:38,140 The second document is still EMR, CTA number and the account value that we want to load. 91 00:05:38,160 --> 00:05:39,450 So this should be covered. 92 00:05:39,450 --> 00:05:46,020 So this will allow us to chinda a delay of 15 seconds until we already configured our timer to operate 93 00:05:46,020 --> 00:05:47,020 on then down. 94 00:05:47,190 --> 00:05:47,540 Great. 95 00:05:47,550 --> 00:05:48,660 Then we proceed. 96 00:05:49,020 --> 00:05:52,140 And let me just call this reset function. 97 00:05:52,140 --> 00:05:52,770 All right. 98 00:05:52,770 --> 00:05:55,380 So we go ahead and call reset. 99 00:05:55,620 --> 00:05:57,960 So this complete the process of configuration. 100 00:05:57,960 --> 00:05:58,350 So what? 101 00:05:59,040 --> 00:06:02,880 What are all things that we did over here so we forcefully stop our timer? 102 00:06:03,270 --> 00:06:04,980 We choose this specific option. 103 00:06:05,010 --> 00:06:08,170 So here we do not want interrupt or not only learn more. 104 00:06:08,400 --> 00:06:14,320 We simply want our time to operate in a normal OK, so we read an existing option that you have for 105 00:06:14,320 --> 00:06:16,770 any timer and then we update an option, right? 106 00:06:17,830 --> 00:06:23,590 We calculated or delay, depending on the time that we are targeting for an application that we are 107 00:06:23,590 --> 00:06:24,400 profiling, right? 108 00:06:24,760 --> 00:06:29,650 So here we are assuming that our function would be taking more than 15 seconds. 109 00:06:29,890 --> 00:06:36,280 So we loaded our timer so that the able to calculate the delay of at least 15 seconds, right? 110 00:06:36,820 --> 00:06:42,310 Then we load that well into the counter and then we are revisiting our time. 111 00:06:42,550 --> 00:06:46,970 So these are the series of steps that you need to perform while initializing your time. 112 00:06:46,990 --> 00:06:53,230 Right now, let's assume that the application that we are profiling is a simple, deliberate death rate. 113 00:06:54,450 --> 00:07:02,460 And this is sending a strong profile on to a council race, so this is what we wish to prove. 114 00:07:02,770 --> 00:07:03,030 Great. 115 00:07:04,190 --> 00:07:09,590 So here we have an application which you want to provide, so just about an application, what we going 116 00:07:09,810 --> 00:07:10,280 with? 117 00:07:10,760 --> 00:07:11,090 OK. 118 00:07:11,360 --> 00:07:14,300 We will be going ahead and we'll be starting our crime. 119 00:07:14,670 --> 00:07:15,050 So. 120 00:07:16,050 --> 00:07:19,140 We call the start function, this required two arguments. 121 00:07:19,140 --> 00:07:25,320 First one is the team, which is against the structure and diversity and no right? 122 00:07:25,680 --> 00:07:31,170 So once you start your timer first, you sample the value at that instant, so let it just call the 123 00:07:31,170 --> 00:07:31,750 gate value. 124 00:07:31,770 --> 00:07:33,730 This return the current value of our time. 125 00:07:33,990 --> 00:07:35,310 So this return you that you do. 126 00:07:35,580 --> 00:07:42,420 So we declared what variable utility this will be storing the clock tick that we have at the start of 127 00:07:42,420 --> 00:07:43,790 our application rate. 128 00:07:43,800 --> 00:07:45,100 So we call get value. 129 00:07:45,150 --> 00:07:46,530 This again required two arguments. 130 00:07:46,530 --> 00:07:51,180 The first one is that here my second one is the DMA number, right? 131 00:07:51,390 --> 00:07:53,580 Then we allow an application to complete. 132 00:07:53,700 --> 00:07:58,440 OK, and then we declared one more variable, which we refer to as an end. 133 00:07:58,770 --> 00:07:59,090 OK. 134 00:07:59,280 --> 00:08:02,730 And that will be sampling the value of. 135 00:08:04,130 --> 00:08:10,130 The counters that we have after we finish the execution of our application right now, you know, that 136 00:08:10,130 --> 00:08:16,110 I counter is going in a downward election rate the stock will have at higher value. 137 00:08:16,110 --> 00:08:17,810 Let's back to it right now. 138 00:08:17,810 --> 00:08:22,910 Let me just try to bring the number of clock ticks that we are consuming data with. 139 00:08:22,910 --> 00:08:26,510 Each clock they are counted will be discriminated by one, right? 140 00:08:26,540 --> 00:08:27,110 This makes sense. 141 00:08:27,140 --> 00:08:28,730 This is how our founder works. 142 00:08:29,100 --> 00:08:34,910 OK, so if we compute the difference between starting in, that basically gives us. 143 00:08:35,970 --> 00:08:41,970 The number of topics that we are consuming to execute this application, right, and that we will be 144 00:08:41,970 --> 00:08:50,550 utilizing to compute the delay rate so the number of OK clock ticks that we are consuming. 145 00:08:50,590 --> 00:08:56,730 OK, let me just bring this in and potentially duty and the value that we want printed. 146 00:08:56,740 --> 00:08:58,410 Start my nursing, right? 147 00:08:58,470 --> 00:09:03,480 If you upgrade your account setting it up well, then in that case then will have an higher value ask 148 00:09:03,480 --> 00:09:04,380 about the stock, right? 149 00:09:04,380 --> 00:09:06,750 So there you need to perform and minus stock, right? 150 00:09:07,530 --> 00:09:14,130 Once you have the number of clock ticks that you are consuming now will do some calculation, right? 151 00:09:14,130 --> 00:09:17,560 So we know that Tariq sativa operates at 100 megahertz, right? 152 00:09:17,580 --> 00:09:19,980 So this basically is equal to 10 industry week. 153 00:09:20,700 --> 00:09:25,610 If you take an inverse of it's a single clocked, it cost us around in this two minus trade. 154 00:09:25,950 --> 00:09:31,380 So if you want to get an equal value in a microsecond, right, so if you just separate, then there's 155 00:09:31,380 --> 00:09:34,230 two minus six and then this minus two, which we did over here. 156 00:09:34,710 --> 00:09:38,490 So then this two minus six will result in two microsecond antennas. 157 00:09:38,490 --> 00:09:41,190 Two minus two will give 0.2 to one, right. 158 00:09:41,400 --> 00:09:44,670 So as soon as we have a number of blocked, it's OK. 159 00:09:44,910 --> 00:09:48,300 If you want to get the value in a microsecond, you just need to multiply by. 160 00:09:48,300 --> 00:09:52,590 The factor of zero point zero zero point zero one is a floating point number. 161 00:09:52,800 --> 00:09:54,630 So we need to proceed. 162 00:09:56,000 --> 00:10:02,660 With the printing function, right, that allow us to print the flirting going, no, it so. 163 00:10:03,940 --> 00:10:05,470 Dying in. 164 00:10:06,640 --> 00:10:13,990 Microsecond rate, or you could just be mentioning like this person 0f this is the format specified 165 00:10:13,990 --> 00:10:17,440 that we use when we want to pay the plotting by number. 166 00:10:17,530 --> 00:10:17,860 OK. 167 00:10:18,130 --> 00:10:24,710 And what we need to do is we just need to perform start mining, saying OK. 168 00:10:24,710 --> 00:10:29,860 And the multiplication factor that we need to add is 0.08, right? 169 00:10:29,860 --> 00:10:32,440 So this is how we will be getting. 170 00:10:33,930 --> 00:10:34,680 The value. 171 00:10:35,930 --> 00:10:41,570 In my view, a second rate, so this is the time our application consuming OK in a microsecond if you 172 00:10:41,570 --> 00:10:44,570 want to bring the value system in a nanosecond rate. 173 00:10:44,960 --> 00:10:50,780 So for a nanosecond, we just need to multiply by 10, and that will basically give us a decision as 174 00:10:50,780 --> 00:10:54,950 to mine so it will be converted into this two minus nine rate. 175 00:10:55,250 --> 00:11:00,560 And this basically signifies that Dennis two minus nine, will give us a nanosecond and the 10 will 176 00:11:00,560 --> 00:11:02,030 be as it is over here, right? 177 00:11:02,300 --> 00:11:07,870 So whenever you want to get the value in nanosecond, you just need to multiply by the factor of 10. 178 00:11:07,880 --> 00:11:10,080 Right now, this is not a floating point number. 179 00:11:10,100 --> 00:11:14,360 So we could proceed with the XL print rate, so let it just go ahead. 180 00:11:15,640 --> 00:11:17,370 And add to bring the. 181 00:11:18,710 --> 00:11:18,980 OK. 182 00:11:19,370 --> 00:11:22,250 And here we will be spending time in. 183 00:11:23,400 --> 00:11:29,490 In a nanosecond rate here, students are no, it's not flirting going, no. 184 00:11:29,790 --> 00:11:32,760 It is a fixed point number, so we could just use percieved zero. 185 00:11:33,480 --> 00:11:33,810 OK. 186 00:11:34,020 --> 00:11:38,280 And here the value that we're going to apprentice start minus st. 187 00:11:38,640 --> 00:11:41,520 OK, and this should be multiplied by the factor of 10. 188 00:11:41,820 --> 00:11:43,890 So this is how we profile our application. 189 00:11:43,900 --> 00:11:47,010 So first, we are calculating the number of clicks. 190 00:11:47,010 --> 00:11:51,060 OK, that should be a start minus it in a case of our download. 191 00:11:53,070 --> 00:11:59,490 OK, and then to calculate the value in an microsecond, we just need to multiply by the factor of 0.01 192 00:11:59,670 --> 00:12:02,370 when you calculate the value in in a nanosecond. 193 00:12:02,400 --> 00:12:04,590 We just need to multiply by the factor of that, right? 194 00:12:04,590 --> 00:12:05,910 So this completes our application. 195 00:12:05,910 --> 00:12:09,210 Let it just proceed to be our application project. 196 00:12:10,600 --> 00:12:15,870 So once our buildings finished, we will be selecting our application project Debug as launch on hardware, 197 00:12:15,940 --> 00:12:16,230 right? 198 00:12:17,580 --> 00:12:19,510 So this will automatically programmers. 199 00:12:20,930 --> 00:12:26,810 So let us try to connect and why this terminal to conflict where we have our hook in the border that 200 00:12:26,810 --> 00:12:28,730 which we would be operating is one one five. 201 00:12:28,970 --> 00:12:29,240 Right? 202 00:12:29,540 --> 00:12:32,440 Only thing that we need to do is to click on resume, but right. 203 00:12:34,200 --> 00:12:36,750 So here we are just calling an inexplicable. 204 00:12:36,780 --> 00:12:42,030 We haven't called the function that perform initialization of a timer and hence we are not seeing any 205 00:12:42,030 --> 00:12:42,570 value for it. 206 00:12:42,930 --> 00:12:49,580 So let me just go ahead and call Primary Nic after we perform the initial addition for and you are very 207 00:12:49,590 --> 00:12:56,790 fit and let's just again rebuild our application and then we need to start afresh DBA configuration 208 00:12:56,790 --> 00:13:00,480 right to select our DBA configuration and click on relaunch. 209 00:13:02,220 --> 00:13:04,780 So now we proceed and click on resume button, right? 210 00:13:05,130 --> 00:13:09,060 So you could clearly see the number of clock ticks that we are consuming is around two. 211 00:13:09,060 --> 00:13:09,940 Forty six. 212 00:13:09,990 --> 00:13:10,350 OK. 213 00:13:10,620 --> 00:13:16,590 And the time that we are getting in a microsecond is two point forty six, whereas time that we are 214 00:13:16,590 --> 00:13:19,460 getting in a nanosecond is two four six zero. 215 00:13:19,490 --> 00:13:19,650 Right. 216 00:13:19,710 --> 00:13:25,140 So this is how we perform a profiling of an application utilizing any set time where it.
