WEBVTT 00:00.150 --> 00:06.630 What we cover next is how we perform an initialization of signal line ready, but rate so signal could 00:06.630 --> 00:07.920 have a multiple value. 00:07.920 --> 00:14.460 It could either be a single day or multiple bad, and we have a large potato in how you handle all the 00:14.460 --> 00:17.610 situation when we consider an initialization rate. 00:17.610 --> 00:21.210 So we will be discussing the different strategies that we have at this rate. 00:21.210 --> 00:23.550 So we will be working with the signal here. 00:23.550 --> 00:28.710 And the theme that we discuss over here are equally eligible for variables, right? 00:28.740 --> 00:30.520 So we start with the signal, right? 00:30.930 --> 00:36.950 Ladies, is you that we first work with the single bit signal, so we declared the name of the signal 00:36.960 --> 00:37.940 estimate, right? 00:38.190 --> 00:39.630 And say this single bit. 00:39.630 --> 00:42.720 So we work with lyricism standard and discord logic. 00:42.840 --> 00:48.900 So whenever we need to specify a single bit, we just need to add standard underscore logic Great Dane 00:48.900 --> 00:51.380 to add an initialization value. 00:51.390 --> 00:54.240 We just start cooler and equals to right. 00:54.780 --> 01:01.500 And then since we have only a single bit value, so we need to use a single word great. 01:01.500 --> 01:08.130 So if you want to initialize them to a value of zero to a single good and then you add seal, right? 01:08.130 --> 01:13.200 So this is how you perform initialization of a template to a value of zero. 01:13.200 --> 01:18.000 If you want to initialize them to a value of one, you just need to add single code. 01:18.270 --> 01:18.490 Right. 01:18.540 --> 01:24.500 So this is how you declared a single bit variable and initialize it to the specific value. 01:24.510 --> 01:30.930 Right now, if you have the multi bit signal in that case, you need to use double code light. 01:31.170 --> 01:34.600 So let's assume we have a team to OK, which is multiple. 01:35.190 --> 01:41.730 OK, so we'd have a series of four pixel standard and this code Logic or Niseko Vector and then three 01:42.180 --> 01:43.610 down to zero later. 01:43.620 --> 01:49.040 This is the size that we have for our time to right now, and we want to initialize it to all zero. 01:49.050 --> 01:55.230 So we are getting that golden equals two no sizes greater than when greater will be utilizing double 01:55.230 --> 01:57.720 code than zero zero zero C, right? 01:57.720 --> 02:03.580 So here the number that we act is by default considered to be net binary format rate. 02:03.580 --> 02:08.910 So for each bit, we'll give you specify one of the binary number to Zoom. 02:08.910 --> 02:17.250 You have some higher sales rate so that you get a 16 bit, so adding a 16 zeros will not be a good idea, 02:17.250 --> 02:17.460 right? 02:17.490 --> 02:24.750 Instead, what we do is we work with a different radix rate, so we work predominantly with that hexadecimal 02:24.750 --> 02:28.750 whenever we have a site greater than eapic rate, certainly. 02:28.770 --> 02:34.140 But you could use a binary red state so you could easily specify eight zeros. 02:34.440 --> 02:40.770 But as soon as your size goes about it, we prefer to go with an hexadecimal red state. 02:40.780 --> 02:48.510 So we proceed like this signal that is a you three is of, say, 16 that creates the standard underscore 02:48.510 --> 02:51.830 logic, i.e. the school vector, right? 02:51.840 --> 02:54.960 And to say is that we are targeting is 16 bit. 02:54.960 --> 02:58.540 So we just need to add down to zero rate. 02:58.540 --> 02:59.790 So we know known to zero. 03:00.300 --> 03:01.640 Mean and equals two. 03:01.680 --> 03:04.320 OK, then we have a double code, right? 03:04.320 --> 03:08.090 Because we have multiple states right now here. 03:08.100 --> 03:13.000 We want to specify the initialize value in an hexadecimal format, right? 03:13.020 --> 03:16.940 So 16bit is equal to four exactly single digit rate. 03:16.950 --> 03:21.750 So to specify an extra decimal value, we add X at the beginning rate. 03:21.750 --> 03:28.320 So just before that about code, you need to add an x ray so that represent the format specified four 03:28.530 --> 03:32.700 and hexadecimal number two add 16 zeros to item three. 03:32.700 --> 03:38.640 We just need to add four zeros because each digit that we specify we're here is an hexadecimal digit 03:38.640 --> 03:41.470 again, that is equal to four binary digit rate. 03:41.490 --> 03:46.500 So for hexadecimal, digit will be equivalent to the 16 binary digit rate. 03:46.500 --> 03:52.870 So this is how you specify the value whenever you have the signal size greater than eight. 03:52.890 --> 03:57.000 But right now, let's assume you have a size greater than 32 bit rate. 03:57.000 --> 04:02.010 So usually we work it now with the values which are multiple of twos, right? 04:02.010 --> 04:06.180 So after 32, we preferably go within 64 bit rate. 04:06.360 --> 04:13.380 So in that case, so if you divide sixty four by four, so you get 16 hexadecimal digit, that is again 04:13.830 --> 04:16.440 a difficult task to add an individual digit rate. 04:16.440 --> 04:20.100 So in that case, to initialize all the bits to a zero. 04:20.130 --> 04:23.490 What we do is we have other metrics already to do. 04:23.520 --> 04:30.230 We have a signal we named it a stand for and it have a size of 128 bit rate, cisgendered and logic. 04:30.450 --> 04:39.190 This vector right to to specify the one weighted birthday state till we date 127 down to zero. 04:39.210 --> 04:39.480 Right. 04:39.480 --> 04:46.410 So this is how you specify 128 bit to initialize all of the bit to a zero at once, right? 04:46.680 --> 04:49.050 What we do is we just had other states. 04:49.050 --> 04:50.580 So this is the key word that we add. 04:50.850 --> 04:54.930 Then we add equals to greater, then rate equals to greater. 04:55.120 --> 04:58.050 And in the single code, we just started C, right? 04:58.080 --> 04:59.850 So what this will do is this will. 04:59.900 --> 05:05.680 Automatically initialize all the bits that we have with the signal. 05:05.710 --> 05:09.250 OK, two words here, right to do that, the four methods that we have. 05:09.580 --> 05:15.760 So in a case of a single bit signal, we just need to use a single code in the case of multiple signal. 05:15.790 --> 05:17.150 You need to use the code. 05:17.170 --> 05:23.830 So till the size of each bit, we would prefer to specify the initialize value in a binary format itself. 05:24.100 --> 05:27.220 But as soon as you have a size created a need, right? 05:27.550 --> 05:34.390 So in that case, we prefer to work with an either radix rate or we prefer to work with an hexadecimal 05:34.390 --> 05:34.800 format. 05:34.810 --> 05:39.010 So each hexadecimal digit is equivalent to four binary digit rate. 05:39.340 --> 05:43.130 And as soon as we have a size greater than 32 bit rate. 05:43.150 --> 05:47.380 So we prefer this method where we rate others then equals to agree to that. 05:47.470 --> 05:51.100 And then we add the value that we want to initialize, right? 05:51.110 --> 05:56.620 So what we do is this will initialize all the bit that we have in the signal to a zero, if you just 05:56.620 --> 05:58.930 specify this to be single code one. 05:59.020 --> 06:05.870 So what this will do is this will initialize all the bit that we have in our vector to see. 06:06.730 --> 06:13.120 So these are the multiple ways that we have with this for adding an initial value to signal and variable 06:13.120 --> 06:13.390 rate. 06:13.390 --> 06:19.330 So all the things that we discuss over here is equally eligible for a variable also, so you could follow 06:19.330 --> 06:23.600 the same method and perform an initialization of variable rate.
