WEBVTT 00:00.150 --> 00:04.610 So this is the call that we have utilized in understanding the future design. 00:05.460 --> 00:12.540 So let us just try to decode so you can divide your code in a three to four spot. 00:12.570 --> 00:14.580 Is this to mean that we have? 00:15.060 --> 00:15.410 Right. 00:15.780 --> 00:23.070 The second part is where we have started an entity and we have ended the term partisan architecture. 00:23.070 --> 00:23.290 Right. 00:23.310 --> 00:26.100 So here we have started an architecture and here we have an. 00:27.560 --> 00:36.020 So the first two lines specify the library that we are utilizing, the library means this is a folder 00:37.070 --> 00:43.220 inside the directory where you have installed of which consists of a set of library. 00:43.240 --> 00:47.720 So out of the set of library, you use this library. 00:47.810 --> 00:49.910 This is what we are specifying. 00:50.960 --> 00:58.920 By adding this to the summary of this two line will be that there exists and took a folder inside of 00:58.920 --> 01:05.500 bravado and we are trying to use one of a library which is present inside that field. 01:05.550 --> 01:09.410 OK, so just to explore, I just show you the. 01:11.510 --> 01:13.430 So this is where I have installed my. 01:14.330 --> 01:21.010 So if you just go inside of me and then you have something called as Nandita, so if you just go inside 01:21.010 --> 01:24.610 the data, we are currently targeting the audience. 01:24.620 --> 01:30.830 So if you just search for Vitya, OK, then you have a ninety three, two thousand eight. 01:30.830 --> 01:31.730 Ansel's right. 01:31.800 --> 01:35.010 So if you just go to a ninety three now, you'll be able to see an item. 01:35.270 --> 01:35.450 Right. 01:35.550 --> 01:41.130 So this is the full and inside this you'll will be finding the libraries, which are pretty great. 01:41.600 --> 01:50.060 So when we are seeing or writing this to line the compiler is basically we are helping a compiler to 01:50.330 --> 01:51.820 invoke this date. 01:51.890 --> 01:53.920 So this is the meaning of the statement. 01:54.260 --> 02:02.270 Then the next day to now, you can see that this is something which is related to a library. 02:02.510 --> 02:02.900 OK. 02:04.760 --> 02:10.790 But this next part that is part number two and number three is purely system dependent. 02:10.820 --> 02:13.190 OK, so library system independent. 02:13.400 --> 02:17.330 OK, but the part two and three is system independent. 02:17.360 --> 02:23.560 So in general, how we distinguish between them is let's assume that you have a system. 02:23.870 --> 02:24.190 Right. 02:24.710 --> 02:25.190 So. 02:26.660 --> 02:33.830 What you can see is the system can be divided into two parts, the first part is where you are considering 02:34.250 --> 02:38.100 the function that your system is performing as a black box. 02:38.100 --> 02:41.330 So what you see from an outside one, right. 02:41.340 --> 02:42.410 So you have a system. 02:42.800 --> 02:44.060 What is inside the system? 02:44.060 --> 02:45.690 We are least fancy. 02:45.830 --> 02:50.030 So we are more concerned about the inputs and outputs that we have. 02:50.060 --> 02:51.350 So this is the first part. 02:51.770 --> 02:59.900 And the second part is when we are least concerned about an output or what is present outside the box, 02:59.900 --> 03:01.520 but instead how we. 03:02.540 --> 03:07.610 Interact between the input people that we have and how we are implementing the logic. 03:07.640 --> 03:09.370 So this represents our second. 03:09.710 --> 03:16.170 OK, so first part is where we specify in the second part is where we are developing energy. 03:16.200 --> 03:18.940 So any system can be divided into two parts. 03:19.550 --> 03:28.070 So the part of Ujjal School where you will be specify the components which are positioned outside the 03:28.070 --> 03:29.450 box is an entity. 03:31.130 --> 03:32.660 OK, whereas. 03:33.520 --> 03:41.740 The part of you still could very well be specifying logic or how direct between input and output is 03:41.740 --> 03:44.020 basically an architecture. 03:45.630 --> 03:48.000 OK, so remember these two things. 03:49.950 --> 03:50.330 OK. 03:51.640 --> 03:59.980 So now here we are implementing an angry try to let us assume that you have your anger to hear, it 03:59.980 --> 04:06.680 consists of two single input puts E and B and we have an output, which is fine. 04:07.060 --> 04:10.440 Again, it also have a dimension of one bitrate. 04:10.660 --> 04:12.020 So A is input. 04:12.030 --> 04:13.360 So we have declared any. 04:14.370 --> 04:21.710 Then comes the direction, which is input and single, which is represented as standard and eschatology. 04:22.230 --> 04:25.270 OK, so this is how you specify a single bit. 04:25.680 --> 04:29.010 Similarly, for also we started to be OK. 04:29.040 --> 04:30.130 Then we have a goal. 04:30.150 --> 04:31.500 The direction is input. 04:31.800 --> 04:35.060 And then since it is single bit so we specify standard. 04:35.850 --> 04:36.050 Right. 04:37.080 --> 04:45.210 Similarly, we need to write why, OK, so that action is output and then single with is specified standard. 04:45.210 --> 04:50.760 And the second one more important point to note is as we complete declaration of all life. 04:51.030 --> 04:55.020 So here, if you see line number six, that is this one. 04:55.110 --> 04:55.440 Right. 04:55.740 --> 04:57.610 So here this is our first output. 04:57.630 --> 05:05.910 So we still have the ports which are remaining to be declared inside this food plot. 05:05.970 --> 05:06.190 Right. 05:06.600 --> 05:13.560 So for that reason, we have added a semicolon more here than we have declared our definably. 05:14.010 --> 05:16.990 But still, we have one board which is yet to declare. 05:17.010 --> 05:17.700 That is why. 05:17.710 --> 05:20.360 So for that reason, we have include semicolon. 05:20.640 --> 05:26.650 But as we complete the declaration of Y, you'll be noticing this is the last output that we have inside 05:26.680 --> 05:27.440 our date. 05:27.900 --> 05:35.010 So once we complete the declaration of the last iReport, we do not need to add a semicolon. 05:35.070 --> 05:41.490 This is how a compiler identify that we have completed the declaration of all the work. 05:41.550 --> 05:42.750 So remember this logic. 05:43.850 --> 05:52.580 OK, then, as you complete an entity, we have acted and we have started an entity and we have ended, 05:52.590 --> 06:00.200 and so this completes the ticking block where we will be defining that part of the system which reside 06:00.200 --> 06:01.670 outside or which use it again. 06:01.860 --> 06:04.310 And that is basically a that you have. 06:04.310 --> 06:04.610 Right. 06:05.510 --> 06:11.000 Then the second part is no, we have completed this declaration of all. 06:11.780 --> 06:14.980 The second part is how you declare the logic. 06:15.020 --> 06:15.300 Right. 06:15.680 --> 06:18.240 So for that, we have the third party. 06:19.160 --> 06:21.080 So we start with an architecture. 06:21.530 --> 06:22.410 Then we are to begin. 06:22.500 --> 06:26.960 Now, there is a specific reason for having a begin inside an architecture. 06:26.990 --> 06:33.440 OK, so whenever you are in the need to have a completely variable, so the space between an architecture 06:33.460 --> 06:36.580 and begin is allocated for that. 06:36.830 --> 06:39.160 So you can add a single here. 06:39.180 --> 06:45.980 You can if you want to use a component, then you can use a component over here and you can also declared 06:45.980 --> 06:47.620 an array or a memory element. 06:48.050 --> 06:54.490 So the space that you'll be finding between an architecture and begin is allocated for this three purpose. 06:54.500 --> 07:01.010 But since our design is so simple that it doesn't require any of this component, so we have not included 07:01.010 --> 07:03.200 anything between architecture and right. 07:04.010 --> 07:07.070 So as we proceed further, you will have a good grasp on this concept. 07:07.460 --> 07:07.760 Right? 07:08.090 --> 07:10.180 So remember, we started with an architecture. 07:10.250 --> 07:15.470 Then we get the space to declare a signal component and the memory element. 07:15.800 --> 07:23.720 Then we start begin to once we begin this new device to a compiler that now we are ready to specify 07:23.720 --> 07:29.840 a logic and then output for us is why we want to implement an operation. 07:29.840 --> 07:32.510 And for us, an operator in IS. 07:33.470 --> 07:41.390 Shows like this, OK, so we need to specify and utilize an operator, and this is how you specify and 07:41.390 --> 07:46.070 equals to it and used it or this is often referred to as an assignment. 07:46.460 --> 07:51.640 OK, so why this basically means not Vittel y equals to be right. 07:51.980 --> 07:55.370 And then we have started an architecture, so we must. 07:56.290 --> 07:59.200 Paint and architecture, so that is done by utilizing. 08:00.130 --> 08:06.940 The aim right now to summarize, OK, so we have a system which we are implementing. 08:07.970 --> 08:14.060 So you divide your system into two parts, so first is you assume that you do not know what is inside 08:14.060 --> 08:14.600 the system. 08:14.810 --> 08:21.320 OK, so you just look at an output or an outside word and that will give us an idea about an input and 08:21.320 --> 08:23.990 output that we have on in system. 08:24.350 --> 08:30.740 So the first part, which is an entity, should consist of a declaration of all the input and output. 08:30.980 --> 08:34.910 OK, so this is all things will be mentioned inside and then. 08:35.390 --> 08:36.740 OK, how we declare them. 08:36.920 --> 08:40.190 Let us assume that you want to implement an Tofig right. 08:40.460 --> 08:40.910 So far. 08:40.910 --> 08:41.170 And how. 08:41.850 --> 08:43.490 And B is. 08:44.940 --> 08:47.540 In a zoo and some men carry it out. 08:47.630 --> 08:50.520 All right, and each is having a series of single. 08:50.730 --> 08:52.140 So we start with an entity. 08:53.550 --> 09:00.240 OK, then let's just name this as an Hafford, right, it's so this is how you start an entity and as 09:00.240 --> 09:03.720 you start an do, the first thing you do is to end an entity. 09:03.720 --> 09:09.150 And you can you can end an entity by utilizing or by referring to the need that you have provided to 09:09.150 --> 09:10.950 an entity that is HAFID. 09:11.130 --> 09:11.460 Right. 09:11.640 --> 09:14.370 And we intend to do so. 09:14.370 --> 09:16.620 You can use uppercase, lowercase. 09:16.620 --> 09:20.970 It doesn't matter then to specify the word between this block. 09:21.230 --> 09:26.130 OK, we use a keyword both OK and in parenthesis, OK. 09:26.640 --> 09:32.150 And then again, a parenthesis and in between the parenthesis will be declaring all the right. 09:32.160 --> 09:35.250 So as we complete our parentheses will be adding semicolon. 09:35.320 --> 09:43.610 Right now we have A and B, so E and B both have A say so we can use a comma to separate them then akula 09:43.710 --> 09:44.960 the direction is it. 09:45.120 --> 09:50.630 And since this is single we will be writing standard on the school lunch. 09:51.300 --> 09:55.980 Now the check is whether this is a class, whether we use our last book. 09:56.040 --> 09:57.210 So the answer is no. 09:57.540 --> 10:00.530 So for that reason we will be adding a semicolon. 10:00.840 --> 10:02.940 Then we have S and C, right. 10:02.940 --> 10:04.830 So that it is declared as. 10:06.710 --> 10:14.990 Direxion is out again a single bit, right, so senators could launch whether this is our last Salu, 10:14.990 --> 10:23.460 so we'll be adding a semicolon then we have a C, OK, Direxion is out standing on the psychologic, 10:23.480 --> 10:24.590 whether this is our last. 10:24.840 --> 10:25.400 Yes. 10:25.910 --> 10:28.790 So we will not be adding any semicolon over here. 10:28.800 --> 10:34.610 So this is how you declare a single bit put to declare a multi. 10:34.640 --> 10:36.770 But the process is very simple. 10:36.770 --> 10:41.860 You specify a direction and along with the logic, you need to add a vector. 10:42.460 --> 10:48.020 So, for example, if you have a series of foubert, if we want to both sides of Foubert, so you just 10:48.020 --> 10:56.560 add three down to see if you want to have a size of 16, then you will be writing standard underscored 10:56.630 --> 10:57.860 logic on this corrective. 10:58.250 --> 11:00.290 Then encyclopaedias is 15. 11:01.010 --> 11:01.300 Right. 11:01.400 --> 11:07.880 So as we progress further, I consider the complex examples that you'll have a good idea about how you 11:07.880 --> 11:10.430 use Ascender the logical disconnect. 11:10.460 --> 11:16.430 Right now you have an idea this will represent our first part that we have declared all the things that 11:16.430 --> 11:18.350 we can see from an outside. 11:18.350 --> 11:19.540 If you consider the. 11:20.800 --> 11:22.830 System logic to be a black box, right? 11:23.290 --> 11:27.490 The second part is where you declare a logic. 11:28.790 --> 11:32.090 Or how your input and output would interact with each other. 11:32.120 --> 11:32.390 Right. 11:32.420 --> 11:34.770 So how do we do that is very simple. 11:34.790 --> 11:36.500 So we start with an architecture. 11:38.370 --> 11:44.950 We given name to an architecture, so usually the practice that we follow is so if this isn't half I, 11:45.830 --> 11:53.410 so I'll just name it as an offer to OK, and this basically belongs to an entity, HAFID. 11:53.540 --> 12:00.290 So architecture have added to this is a user defined name for an architecture of an entity. 12:00.770 --> 12:01.490 It is. 12:02.030 --> 12:04.760 And now we have started an architecture. 12:04.760 --> 12:08.270 So we will end an architecture by referring to its name. 12:08.270 --> 12:08.510 Right. 12:08.530 --> 12:18.560 So it should be better to then we get the space where we can declare a signal component or of memory 12:18.560 --> 12:18.940 element. 12:19.220 --> 12:24.800 But if you do not have anything like this in our design, so we can directly proceed with the great 12:25.040 --> 12:30.340 so far Hoffner that we do not required any temporary variable or a component or a memory. 12:30.350 --> 12:33.140 So we'll just try to begin right then. 12:34.240 --> 12:42.190 For some, we know that it should be a Salvy so will use as equals to the. 12:43.130 --> 12:51.140 For an export, we haven't operated like this so far and then they don't carry should be kwassa and. 12:52.980 --> 12:53.220 We. 12:54.510 --> 13:01.740 Right, so equals two is more or less than it was to I is acting as an assignment operator and unleashed. 13:02.730 --> 13:06.240 So this is how you feel, right? 13:06.480 --> 13:15.690 So this completes the second part where we decide our ecological input and output to interact with each 13:15.690 --> 13:21.960 other, whereas the first part we will just be specifying what are the inputs and outputs put that we 13:21.960 --> 13:29.880 have inside to remember that the first two lines, OK, which are system independent, will remain common. 13:30.060 --> 13:30.420 OK. 13:31.450 --> 13:34.690 So in most of the cases, you'll be finding that this. 13:36.080 --> 13:42.920 First part of the good independent, the system independent party will remain committed to lump. 13:44.960 --> 13:51.920 The course only the differences will be finding when we actually start implementing second and third. 13:52.190 --> 13:59.000 OK, so standard and logic underscore one one six four have all the definition related to the center 13:59.000 --> 14:01.370 and the school logic data as well as. 14:02.380 --> 14:10.030 The zoological operation that we are utilizing, so in general, the libraries that we use is first 14:10.030 --> 14:14.720 one is standard under school logic and the underscore one one six four. 14:14.740 --> 14:22.450 So that consists of all the declaration of code logic, which is one of accommodator like that, will 14:22.450 --> 14:23.830 be frequently utilizing. 14:23.830 --> 14:29.710 And it will also be consisting of all the logical operations which are defined. 14:30.820 --> 14:37.780 For sectarian cold logic, right, detailing the library that will be using this new. 14:39.220 --> 14:39.850 Stand. 14:40.520 --> 14:48.610 OK, so this library consists of all the arithmetic operations that we want, but this library required 14:48.610 --> 14:50.370 the support of other libraries. 14:50.380 --> 14:59.230 So when we are concentrating on our operations so the input can be of Sindi and can also be on S.A.G. 14:59.740 --> 15:03.530 and both will lead to different creation of a different part of it. 15:03.550 --> 15:03.790 Right. 15:04.060 --> 15:06.490 So unsane operation will have a different hive. 15:06.490 --> 15:07.760 They were assigned operation. 15:07.770 --> 15:12.040 We will have a different hardware because we need to also handle the same bitrate. 15:12.220 --> 15:18.410 So the numeric standard library is used in combination with another library. 15:18.430 --> 15:26.580 So depending on the type that you are targeting, you need to include standard and the school logic, 15:26.740 --> 15:28.210 the school unsane. 15:29.580 --> 15:36.660 OK, so we are working predominantly on an no, or it can either be site. 15:37.850 --> 15:42.420 OK, so these are the four common libraries that we will be using throughout the course. 15:42.440 --> 15:46.020 In fact, you can talk to any system out of this food library. 15:46.040 --> 15:48.290 We rarely use any other library. 15:51.000 --> 15:54.110 For implementing the system one in Fiji. 15:54.200 --> 15:54.750 OK, so. 15:56.040 --> 16:00.560 In general, for most of their application, this would likely will work fine, so standardless, CoreLogic 16:00.570 --> 16:04.370 underscore one one six four numerics and then unsane. 16:04.920 --> 16:08.960 OK, so the first four lines will remain common. 16:09.060 --> 16:11.780 OK, so this will remain common for all the system. 16:12.030 --> 16:19.500 Only the second and third part will be ready and then you need to focus more. 16:19.900 --> 16:26.100 OK, and our agenda will be to focus more and more to centralize the logic instead of just. 16:29.720 --> 16:38.150 Repeating the OK, so now you have a good idea about how the world works and we successfully able to 16:38.150 --> 16:41.510 actually decode the more insight into issue. 16:41.840 --> 16:49.830 Right now you try to attempt an assignment so that you also able to get more insight into our future. 16:50.240 --> 16:50.540 Right.
