WEBVTT 00:00.360 --> 00:06.750 Now what we will do was we will start understanding how to use an automatic operator within N.S.A. in 00:06.750 --> 00:07.800 day to day, Rachel. 00:07.890 --> 00:11.370 First thing that we do is to include the mandatory library search. 00:11.370 --> 00:17.160 So if we plan so if we plan to work with an unsigned order signed today, right, so we won't be required 00:17.160 --> 00:22.740 to use I Tripoli Dot Numeric Standard. 00:22.940 --> 00:30.330 Dartmouth did include all the operator definition, as well as it also include the definition for our 00:30.480 --> 00:31.500 site and unsigned. 00:31.920 --> 00:37.760 Now we proceed and declared signal's right, so we required to operate, which will be acting as the 00:37.800 --> 00:38.760 data source for us. 00:38.760 --> 00:40.860 So we proceed with the signal, right? 00:41.130 --> 00:47.250 Let it just use the run rate and first operate with an unsigned data. 00:47.380 --> 00:50.200 Right now, we need to specify the size range. 00:50.220 --> 00:55.620 So let's assume that we want to operate with a fool, but I'll print state. 00:55.620 --> 01:03.360 So this should be three down to zero rate and will be initially using this to let assume one zero zero 01:03.360 --> 01:04.140 zero rate. 01:05.220 --> 01:10.050 We required one more operator OK, which will serve as the second input for our making block. 01:10.050 --> 01:13.380 So deemed to be OK again unsigned. 01:14.340 --> 01:16.520 OK and sage will remain same. 01:16.530 --> 01:19.260 There is three down to the zero rate. 01:20.190 --> 01:23.620 The registry initialized is two zero one zero zero. 01:23.820 --> 01:30.540 Right then the result of little will be of six five victory because forward will be allocated for a 01:30.540 --> 01:33.840 sum and one bit will be allocated for a cardio great. 01:33.870 --> 01:36.240 Similarly, if we consider subtraction. 01:36.480 --> 01:41.940 OK, so the result of satisfaction will be forward and one which we need to allocate for a bar. 01:42.000 --> 01:42.260 Right? 01:42.630 --> 01:49.320 So both the variable, which will be holding the result of addition and subtraction, must be all size 01:49.770 --> 01:50.280 VIPIT. 01:50.550 --> 01:55.860 And if you consider a multiplication operation, so the size of variables should be at least twice the 01:55.860 --> 01:57.360 size of our opening right. 01:57.630 --> 02:03.810 So here are all printed off size for weight, so the variable which will be holding the result of multiplication 02:03.810 --> 02:05.910 should be at least eight bit inside state. 02:05.910 --> 02:06.930 So just go ahead. 02:07.230 --> 02:11.560 Now we know that addition and multiplication would have a size of five it. 02:11.580 --> 02:15.660 So we just could signal, OK, let's just declare a variable add. 02:16.110 --> 02:16.500 OK. 02:16.560 --> 02:22.770 This will be holding the result of addition, and some of which will be holding the result of subtraction. 02:23.130 --> 02:23.490 OK. 02:23.550 --> 02:25.710 Again, and say OK. 02:25.710 --> 02:32.500 And this should be of size five with rates of four down to zero and will be initializing this to all 02:32.650 --> 02:32.880 see. 02:33.990 --> 02:38.880 Similarly, the variable which will be holding the result of multiplication, we'll just be naming it 02:38.880 --> 02:39.960 as modeled, right? 02:40.320 --> 02:48.060 Again, and say in this case, it should have at least a size of seven down to zero that is e betrayed 02:48.540 --> 02:51.110 that it just initialized this to a zero no for a need. 02:51.120 --> 02:57.420 Maybe we could just use this suffix as the x ray and then we could just add to zero state. 03:00.030 --> 03:05.700 So this basically mean we are specifying the initialization value and then hexadecimal format, right? 03:05.710 --> 03:08.400 So once we complete the declaration of the signal. 03:08.430 --> 03:10.590 Now we know that we want to work with the signal. 03:10.830 --> 03:16.030 So the type of reader that will be utilizing is the signal assignment operator, right? 03:16.050 --> 03:17.490 So let's proceed with an add. 03:17.770 --> 03:23.710 Now we need to make sure that the size that you have on an elite, you then added just matches because 03:23.710 --> 03:26.190 visually the strongly typed language, right? 03:26.220 --> 03:33.440 So when we consider this addition, so addition is of s it right, and if we consider D in one plus 03:33.470 --> 03:36.510 d into so both have a size of four bit Rachel. 03:36.820 --> 03:43.020 Not just you'll, you'll be noticing that we have a size of orbit, whereas on an elegies we have a 03:43.020 --> 03:44.060 size of Typekit great. 03:44.070 --> 03:47.280 So in this case, the good idea will be to match your size at eight. 03:47.280 --> 03:50.040 So how you might just say this, you are pendency, right? 03:50.370 --> 03:53.550 So Dean went to append anything with a variable. 03:53.550 --> 03:58.370 So we have an ampersand operator in vista rates that will be appending zero. 03:58.390 --> 04:01.980 And then I say to a single zero single could see, right? 04:01.980 --> 04:05.570 So this is how you can work for a bit variable to a fiery trade. 04:05.580 --> 04:09.150 So what we are doing here is we are appending zero. 04:09.330 --> 04:15.240 OK, I then it must be all five variable rates assimilating will be falling for the into. 04:15.270 --> 04:15.870 All right. 04:15.870 --> 04:22.530 So this will make sure that we have a theme size on an allergist as well as our interest rate, and 04:22.530 --> 04:24.680 we won't be getting error at a later date. 04:24.790 --> 04:25.070 Three. 04:26.340 --> 04:29.860 So this complete the expression for an add variable. 04:29.880 --> 04:37.110 Now we proceed and just copy this expression that will be replacing add with subtraction right down. 04:37.110 --> 04:43.570 In this case, we just need to replace this operator with minus three and four and multiplication. 04:43.590 --> 04:43.890 Right. 04:43.890 --> 04:48.270 So we just need to add the one cross to two, right? 04:48.270 --> 04:49.020 So this makes sense. 04:49.020 --> 04:55.500 So if you compute the multiplication to forbid multiplication and less requested bits say so here we 04:55.500 --> 04:57.360 get a little bit reserved and here are two. 04:57.360 --> 04:59.280 We created a great so. 04:59.430 --> 05:01.410 We already have a match to take, right? 05:01.680 --> 05:04.130 So let me just see what quote, right? 05:04.140 --> 05:09.630 So here you could clearly see a green indication indicating that we are correctly following the language 05:09.630 --> 05:10.500 syntax today. 05:10.540 --> 05:14.010 Now we go ahead and try to perform a simulation. 05:14.010 --> 05:18.480 So we all really set this source code as stopping the simulation thought. 05:18.480 --> 05:23.640 So we could just proceed to perform runs simulation and perform a behavioral simulation. 05:28.270 --> 05:33.610 Now, if you observe, right, so we have, Dean, when is it and into us four, right? 05:34.060 --> 05:36.430 So eight plus for sure that it's early to tell. 05:36.490 --> 05:42.400 So if we just right click on an ad and change the ratings to an unsigned decimal, right, so you would 05:42.400 --> 05:44.680 clearly know this, we get the value of it, right? 05:45.280 --> 05:50.350 The result of the extraction is eight minus four will give us four right and eight for the. 05:50.590 --> 05:52.430 We get hexadecimal 20 right. 05:52.440 --> 05:57.910 So to get an unsigned decimal, just right click on the bus and select 19 decimal and you'll be able 05:57.910 --> 05:59.170 to notice 32, right? 05:59.470 --> 06:04.630 So this is how you perform and are mighty operations with an operator and an unsigned at a rate. 06:04.630 --> 06:12.430 So whenever you have lattices you here since the value is greater than the two, right? 06:12.430 --> 06:14.290 So we are getting the positive result. 06:14.290 --> 06:20.770 But if you assume that being one is having a lower value as compared to the into, in that case, we'll 06:20.770 --> 06:26.860 be getting the boost compliment value right, which we need to convert to the respect to decimal number. 06:26.980 --> 06:30.250 So let me just give a try to it to replace this with the into. 06:30.670 --> 06:32.920 And then here we have Dean right now. 06:32.920 --> 06:38.080 You could clearly see we are performing the subtraction between Dean two and Dean went right to Dean. 06:38.080 --> 06:41.140 Two is having a lower value as compared to Dean one, right? 06:41.440 --> 06:45.520 So we'll just see what line relaunch a simulation. 06:45.940 --> 06:47.880 So now if you observe, right? 06:47.950 --> 06:54.550 So eight plus four, 12 again addition will be seem OK, multiplication will be seen, but no, here 06:54.790 --> 07:00.090 if we just change the relics to a binary for our subtraction. 07:00.100 --> 07:04.150 So we are getting a value of one one one zero zero, right? 07:04.150 --> 07:09.670 So the value that we received is one one one zero zero. 07:09.700 --> 07:09.970 Right. 07:10.240 --> 07:15.100 So whenever we have one over here that basically indicate that it is a negative number. 07:15.250 --> 07:21.910 So this basically indicates that it is negative number and to get an equal in value, we need to find 07:21.910 --> 07:23.230 out the two compliment, right? 07:23.230 --> 07:25.680 So we have this resolved rate. 07:25.690 --> 07:32.830 So first we get one compliment by complimenting every bit that we have in reserve ratio zero zero zero 07:33.070 --> 07:33.760 one one. 07:34.050 --> 07:34.270 Right. 07:34.270 --> 07:36.040 So this is one compliment. 07:36.340 --> 07:40.030 Now we just need to add one to it to get to compliment, right? 07:40.050 --> 07:45.580 So when and when will it be zero and decision to carry when one will again be a zero? 07:45.610 --> 07:47.710 This will again generate a carry. 07:47.740 --> 07:51.790 So zero plus one use one and then we get two zeros, right? 07:52.120 --> 07:57.370 So if you just find out an equal and decimal value, so it is four. 07:57.410 --> 07:57.700 Right. 07:57.700 --> 08:01.020 So the result is basically minus four. 08:01.030 --> 08:07.360 And if you observe what we are doing is so our D into is having a value of four and in one is having 08:07.360 --> 08:08.350 a value of eight, right? 08:08.680 --> 08:14.740 So we are basically performing four minus eight and they should give us minus four, right? 08:14.740 --> 08:16.540 And this is what is happening over here.
