WEBVTT 00:00.210 --> 00:05.910 So before actually starting to understand FPGA architecture, it becomes necessary that you understand 00:05.910 --> 00:12.900 how the integrated circuit have developed its capability right from the fundamental building devices 00:12.900 --> 00:18.490 that we have to transition to a superior design finally to an OK. 00:18.540 --> 00:23.520 So for that reason, we will cover some of the fundamentals and then will actually proceed to an FBI 00:23.530 --> 00:30.630 architecture so that we will able to understand why FPGA have that kind of a structure. 00:30.660 --> 00:36.060 OK, so we'll proceed with, let us suppose, very simple equation and that to know some. 00:36.810 --> 00:44.580 So let's assume we have a function F OK, that depends on two variables, A and B and which is specified 00:44.600 --> 00:49.310 in some summation and it is equal to zero. 00:49.890 --> 00:55.680 OK, so what this means is when we consider something as a somewhat vertical, so we have to input A 00:55.800 --> 01:03.570 and B and then we have a function F, OK, so and B since they are two variables, they can have four 01:03.570 --> 01:05.420 combination for unique combination. 01:05.460 --> 01:10.410 They can either take a value of zero zero, they can also take zero and they can also take a value of 01:10.410 --> 01:11.700 one zero or one. 01:11.880 --> 01:12.140 Right. 01:12.200 --> 01:14.470 So this is equivalent to the simple zero. 01:14.520 --> 01:16.310 This is equal to decimal one. 01:16.650 --> 01:17.820 This is equivalent to this. 01:17.930 --> 01:20.370 And this is finally equal to. 01:21.390 --> 01:23.610 So when we have an equation. 01:23.610 --> 01:27.030 So the number that we mentioned inside the parentheses, the value of one. 01:27.060 --> 01:32.290 So for us, the table will be this will take a value of one, whereas this is zero. 01:32.670 --> 01:33.350 This is one. 01:33.360 --> 01:34.440 And this is a zero. 01:35.320 --> 01:43.360 Right now, if you just try to implement this with the basic logic, then you'll be noticing we have 01:43.420 --> 01:51.370 one in this combination who ever got Beeber and then we have one over here that is E! 01:52.240 --> 01:54.030 And then we have a beep. 01:54.280 --> 01:54.620 Right. 01:54.820 --> 01:58.090 So this is what an equation looks like for. 02:00.020 --> 02:07.070 Now, if you can implement, you can further simplify this equation, but let's assume that we are not 02:07.070 --> 02:08.400 simplifying this equation. 02:08.900 --> 02:10.760 We want to just implement it, right? 02:10.760 --> 02:14.430 So implementation of this will be so we have an E. 02:15.000 --> 02:18.450 OK, but and Veber, which is available. 02:18.590 --> 02:18.980 OK. 02:19.010 --> 02:21.560 And then we need to first perform an ending. 02:22.300 --> 02:22.660 Right. 02:23.000 --> 02:27.540 And second one is E and then we have a B which is available. 02:27.650 --> 02:29.870 Then we again perform an ending between them. 02:30.590 --> 02:32.320 Finally we will do. 02:32.330 --> 02:32.680 And. 02:32.690 --> 02:34.220 All right. 02:35.630 --> 02:43.550 And then we get so we'll be noticing all the combinations can easily be implemented with and and in 02:43.550 --> 02:53.680 fact we we we always would be having to input and sometimes you might require more and both second and 02:53.780 --> 02:54.430 all right. 02:54.650 --> 02:56.120 But then one thing. 02:56.120 --> 02:57.710 You all can agree that. 02:59.200 --> 03:05.880 I don't know itself are capable of implementing all the combination of traits. 03:06.880 --> 03:10.960 To now let us assume that we go to a market to find out how to implement this. 03:11.310 --> 03:15.790 So we need to find out an actual integrated circuit that have this kind of functionality. 03:16.120 --> 03:17.460 And then we wish to implement it. 03:17.470 --> 03:23.610 Right, to require a button beeber like we require then it and then we also required an R, right. 03:24.010 --> 03:30.460 So we search for the shooter and we found out the three components that are pretty much useful for us. 03:30.490 --> 03:34.610 So this is seven four zero four Hick's inverter. 03:34.660 --> 03:36.290 So consist of six, not eight. 03:37.120 --> 03:38.680 We also have. 03:39.610 --> 03:47.380 Seven four zero eight, which is hard to include, engaged, right, and then we also have a car or 03:47.860 --> 03:52.110 gate inside a single SUV to seven, four thirty five. 03:52.430 --> 03:53.830 So we're required to have any. 03:53.830 --> 03:57.100 And so we'll be making a connection over here. 03:57.130 --> 04:01.020 So from this, we will be getting any better outrage. 04:01.030 --> 04:07.630 So this will be Aniba similarly will be feeding Buhera here and we'll be getting a Bieber out here. 04:07.940 --> 04:13.450 OK, so once we have a warrant be available, we will implement the first level of our search. 04:13.600 --> 04:19.450 And that is actually what we want is the first combination that we require to feed folks who will just 04:19.450 --> 04:23.140 try to change it so that things won't be. 04:24.860 --> 04:27.860 Much complicated, Greg, so this Eva. 04:28.750 --> 04:35.170 And then we have a river that will be the first connection that we will be making, a second connection 04:35.170 --> 04:37.620 is between A and B, right? 04:37.660 --> 04:40.190 So we have a deal here. 04:40.240 --> 04:42.850 So this is a second connection that we'll be making. 04:42.850 --> 04:45.130 And then again, we require the beeber. 04:46.360 --> 04:51.670 So this completes the first level of a circuit and then we proceed to the second level where we just 04:51.670 --> 04:56.490 need to order that so we will be connecting this to our target. 04:56.500 --> 05:02.620 And finally, this two are on contract and this is what will be right. 05:03.740 --> 05:10.280 Now we'll be noticing the likes that we have utilized have a fixed functionality, so for example here. 05:11.330 --> 05:19.280 We have utilized only to not go to arrest for not yet remain unused here to engage Gates, unused civil 05:19.280 --> 05:21.400 military targets are on strike. 05:22.280 --> 05:28.730 So when we consider an integrated circuit, I do not have a reprogrammable capability will be noticing. 05:29.630 --> 05:31.920 We do not fully utilize the company. 05:31.970 --> 05:37.370 OK, so that is the first advantage that we have when we consider Lenarcic or an integrated circuit 05:37.370 --> 05:39.050 with a fixed functionality. 05:39.230 --> 05:49.430 OK, so if this icey could have reprogrammable capability and if we can convert this unutilized algate 05:49.700 --> 05:57.110 to argue it or not, good, we might have much, much smaller circuits if we compare this with this 05:57.260 --> 05:59.270 circuit that we have implemented right now. 05:59.780 --> 06:00.590 So very first. 06:01.620 --> 06:08.250 Difference you'll be noticing between an FPGA and an asset is actually have a fixed functionality, 06:08.280 --> 06:13.730 which cannot be change, which cannot be change or alter during your entire lifetime. 06:14.910 --> 06:22.350 But as FPGA, if some of the blocks are unutilized, that block can actually be reprogrammed or reconfigure 06:22.350 --> 06:25.260 to attain certain different functionality. 06:25.980 --> 06:28.530 So this is the first advantage that we see now. 06:28.530 --> 06:36.640 You notice that the first condition that we will be making is how we can make this and then our reprogrammable. 06:36.660 --> 06:40.960 And that basically leads to three kind of a circuit. 06:40.970 --> 06:49.600 So we have Biram, OK, we have people and we have the light. 06:50.220 --> 06:51.890 So this is where we have started. 06:51.900 --> 06:56.250 So we identify the disadvantage that we have with a fixed. 06:56.250 --> 06:56.700 I see. 06:56.710 --> 07:05.700 And we started to transit to have a reprogrammable capability for an AC so that the unused blocks can 07:05.700 --> 07:09.320 be utilized to implement certain other functions.
