WEBVTT 00:00.180 --> 00:05.400 Before we start discussing about the convergence between the different today. 00:05.460 --> 00:11.280 Let us just proceed to understand what are the different ways we have to perform at major operation 00:11.280 --> 00:17.070 rates whenever you are in a situation where you want to implement an automatic blow in aviation. 00:17.100 --> 00:25.180 OK, so we have multiple alternatives with a rate so we could use standard underscore logic and the 00:25.200 --> 00:25.610 score. 00:26.250 --> 00:26.760 All right. 00:27.040 --> 00:29.100 So this is one of the packages that we have. 00:29.430 --> 00:37.230 We have standard and the school logic on this score and saying, OK, so this is an another package 00:37.230 --> 00:38.010 that we have. 00:38.430 --> 00:45.750 We also have standard analytical logic on the score, saying OK, and the last one which we will be 00:45.790 --> 00:49.380 preferring were all the other packages, the numeric standard. 00:49.980 --> 00:50.310 OK. 00:50.550 --> 00:55.520 The advantage that we get with the numeric standard is this is almost supported by all the FPGA vendors, 00:55.520 --> 01:00.060 so independent of the tools that you will be utilizing if you include this package. 01:00.100 --> 01:06.510 OK, so the code will be all based on desirable independent of the vendor specific tools that we are 01:06.510 --> 01:07.380 utilizing, right? 01:07.920 --> 01:13.590 And in the case of an automatic operation, the preferred data type will always be right. 01:13.610 --> 01:14.670 So remember this? 01:15.090 --> 01:18.690 So preferred leader, I will always be on st. 01:19.680 --> 01:25.830 On Saint or Saint, Rachel will not be working with the standard and the school logic on the school 01:25.830 --> 01:26.280 victory. 01:26.370 --> 01:31.080 So if you want to work with Standard and the school Lord, you're going to school victor and utilize 01:31.090 --> 01:32.520 the automatic operator. 01:32.530 --> 01:35.850 Then you need to include either this or this library. 01:35.850 --> 01:37.800 So if you are working with an on, say, No. 01:38.010 --> 01:42.000 Two and working with the standard industrial logic and school victory today. 01:42.000 --> 01:46.340 So you need to include standard logic on same package. 01:46.350 --> 01:51.720 If you want to work with the same number with standard analytical logic and disco vector D. DeLay, 01:51.780 --> 01:57.170 then you need to include standard and disco logic on the school, saying if you are simply working with 01:57.180 --> 02:02.820 signed in and say, OK, you just need to include numeric standard rate, you will not be utilizing 02:02.820 --> 02:04.500 standard on this logic and disco. 02:05.120 --> 02:09.600 OK, because everything that you achieve with this library could be achieved with any one of tests. 02:09.810 --> 02:12.570 Sure, we did not worry about this library, right? 02:12.810 --> 02:18.120 Even though if you want to utilize this, so whatever operated that we discuss, considering this free 02:18.120 --> 02:21.650 libraries are equally eligible for the results, right? 02:21.690 --> 02:24.690 So you could use the same operator with this library. 02:25.860 --> 02:26.130 Right. 02:26.460 --> 02:30.500 So when we consider signing and saying data, right, so we'll just be discussing the range. 02:30.510 --> 02:36.300 So most of the tools will support for an unsafe to go from zero to Tuileries to 32, right? 02:36.300 --> 02:38.430 So this represent our individual range. 02:38.730 --> 02:42.840 They don't represent the what is the maximum number that you could hold, right? 02:42.850 --> 02:46.050 So the maximum size that you would declare is insane. 02:46.620 --> 02:46.920 OK. 02:47.520 --> 02:50.650 Thirty one down to see right. 02:50.720 --> 02:54.070 At least most of the tool will support this size, right? 02:54.300 --> 03:02.010 Similarly, sign will also have a maximum size of 32 bit rate, so you went down to zero. 03:02.220 --> 03:07.590 Now we'll just be discussing how the numbers are represented, saying Rachel highly, and I'm saying 03:07.590 --> 03:08.340 it's pretty easy. 03:08.340 --> 03:16.320 For example, if you have unsigned three down to zero and we need to randomly find the integer equivalent 03:16.320 --> 03:17.220 of the number right. 03:17.220 --> 03:20.130 So let's assume our value is one zero zero, right. 03:20.140 --> 03:27.930 So this is equivalent to now this is an S. So all of the bits will be used to calculate the equivalent 03:27.960 --> 03:28.830 digital value rate. 03:28.830 --> 03:32.580 So this is equal to eight if you have something like this one zero one zero. 03:32.820 --> 03:37.230 So this will be equivalent to 10 if you are zero zero one one. 03:37.290 --> 03:39.390 This will be equivalent to three. 03:39.840 --> 03:40.650 This is pretty easy. 03:40.650 --> 03:46.380 So this follow exactly the same rule that we use to convert binary to the symmetry. 03:46.410 --> 03:49.800 So this is, you know, how we work with the same digit, right? 03:49.800 --> 03:55.560 So we have signed today and again the size of three down to zero. 03:55.560 --> 04:00.660 We'll just be considering, for example, just to understand an entire process of how you handle a positive 04:00.660 --> 04:01.820 and negative number, right? 04:01.830 --> 04:07.840 So whenever we have a negative number, we need to use the two compliment method to get an equal number 04:07.840 --> 04:07.980 right. 04:08.000 --> 04:12.960 So for example, this is you for this forward, we have this value one zero zero zero. 04:12.970 --> 04:19.050 So whenever we see one at enemies' be built, this basically represent our number is negative, right? 04:19.350 --> 04:21.900 So to get an equivalent value, we need to follow. 04:22.230 --> 04:25.320 We need to calculate the to compliment value of this right? 04:25.650 --> 04:28.860 So first, let it just invert all the bit. 04:28.860 --> 04:33.500 So if you invest all the weight, you get zero for this one and then three, right? 04:33.960 --> 04:39.150 This will give us one compliment and then we just need to add one to it to get two complementary to 04:39.170 --> 04:40.950 the one, one and C2. 04:41.160 --> 04:42.660 Here we get to carry again. 04:42.660 --> 04:45.120 We get to zero again, we get carry zero. 04:45.120 --> 04:45.850 And then what? 04:45.870 --> 04:46.200 Right. 04:46.470 --> 04:51.570 So this is equal to this is equal to eat right. 04:51.570 --> 04:54.200 And since we have won it and and MSB. 04:54.210 --> 04:58.410 So this basically represents that it is minus eight right now. 04:58.410 --> 05:02.390 If you consider we have something like this zero one one one, right? 05:02.400 --> 05:05.280 So since MSP, which is zero. 05:05.400 --> 05:05.570 Right. 05:05.580 --> 05:06.660 So this is positive. 05:06.840 --> 05:12.240 And then you just need to calculate an equivalent of the so equivalent of this is seven, right? 05:12.510 --> 05:17.070 So this is how you calculate the value when you have won it and it must be addition. 05:17.070 --> 05:17.760 A. Right. 05:17.760 --> 05:18.930 And must be graduation, right? 05:19.230 --> 05:25.890 So whenever you have an automatic operation to be implemented in an ideal, prefer to go with 10 signed 05:25.890 --> 05:27.120 or unsigned d today. 05:27.330 --> 05:28.700 Now this is you. 05:28.980 --> 05:35.490 You have implemented a system considering the signed and untainted rates of the output of the system 05:35.490 --> 05:36.360 is on st. 05:36.450 --> 05:36.720 Right. 05:36.870 --> 05:44.760 But you have designed your system such that so it is that you want to send the output in in standard, 05:44.790 --> 05:48.250 and it's called logic on the score vector format, right? 05:48.280 --> 05:49.740 So this might be situation. 05:50.010 --> 05:50.370 OK. 05:50.670 --> 05:56.210 So in that case, what you could do is you have your own st out from this automatic block, right? 05:56.220 --> 05:57.600 So this is an automatic block. 05:57.840 --> 06:00.060 You could just add up and whatever block, right? 06:00.150 --> 06:03.360 So you could just perform a conversion, OK? 06:03.360 --> 06:07.530 And this will automatically give a standard and the school logic on the score vector, right? 06:07.530 --> 06:12.930 So we will be discussing how you perform the conversion from different today and what are the frequently 06:12.930 --> 06:17.330 used and vision that we acquired while designing a system, right? 06:17.340 --> 06:19.030 So these are some of the fundamental of. 06:19.330 --> 06:25.540 Signing on same day, I remember some of the package, which are useful to perform an automatic operation 06:25.540 --> 06:29.980 are standard underscore logic, underscore I. 06:31.410 --> 06:36.840 These are not frequently utilized when we consider that we are doing in tool also, we do not prefer 06:36.840 --> 06:37.320 this, OK? 06:37.470 --> 06:45.780 So the most preferred library when we work with an automatic operation in Nevada is the numeric numeric 06:46.080 --> 06:52.140 standard and the most powerfully today, whenever you are targeting an automatic operation is to go 06:52.140 --> 06:59.700 within and say OK or say OK, do not prefer to go with the standard and the psychological tests, go 06:59.700 --> 07:01.650 back to the other library. 07:01.680 --> 07:05.460 Let's assume you want to work with standard and psychological and physical vector. 07:05.640 --> 07:13.470 So we do have a do package which allows usage of an automatic operator with a standard, and this could 07:13.480 --> 07:15.030 logically list correctly today. 07:15.300 --> 07:16.140 So they are. 07:16.230 --> 07:21.220 If you want to work with an on say device, you just need to include this package that is standard and 07:21.230 --> 07:22.770 the psychological discrepancy. 07:23.220 --> 07:30.660 So this allows us to perform an automatic operation with standard underscore logic and the score vector 07:30.660 --> 07:36.010 to either package that we have it as a standard analytical logic on the score side. 07:36.480 --> 07:36.740 Right. 07:36.770 --> 07:43.380 So this allows us to perform an automatic sound operation with standard underscore logic, underscore 07:43.440 --> 07:43.900 vector.
