WEBVTT 00:00.560 --> 00:05.830 Hello, my name is Typhoon, and in this lecture you will learn about the jump if greater or equal. 00:05.840 --> 00:14.960 So the G instruction is typically used in the context of branching or decision making within a program. 00:14.960 --> 00:21.320 So it enables the program to alter its flow of execution based on a certain condition. 00:21.350 --> 00:26.540 Specifically, when a value is greater than or equal to another value. 00:26.570 --> 00:36.440 So intriguingly, the instruction g ge beckons us with the promise of jump if greater or equal. 00:36.440 --> 00:44.690 So this command boasts an intimate understanding of ex or operation between the sign flank s f and the 00:44.690 --> 00:46.630 overflow flag or f. 00:46.670 --> 00:54.980 So when they're harmonious interplay yields zero a pronounced declaration equals so the result is neither 00:54.980 --> 00:56.630 less or nor equal. 00:56.630 --> 01:06.200 So crafting an elegant narrative GE stands as a testament to our mastery over signed comparisons where 01:06.230 --> 01:09.700 greatness or equality reigns. 01:09.710 --> 01:15.950 So now we will also create another coding example for this here and. 01:16.950 --> 01:17.890 Uh, in here. 01:17.890 --> 01:19.780 We will also create a two value. 01:19.930 --> 01:21.970 So let's get started. 01:21.970 --> 01:31.420 So section, let's, uh, section data here we will create a define it with, with a value of, uh, 01:31.420 --> 01:36.370 30 value one to be 30. 01:36.790 --> 01:42.490 And we will define another, another byte with the value of 30 again. 01:42.520 --> 01:43.570 Value. 01:45.190 --> 01:51.660 To TB 30 and we will create a section text. 01:52.260 --> 01:53.580 And global. 01:54.670 --> 01:55.810 Start here. 01:56.290 --> 01:59.050 So in start we will write this. 02:15.880 --> 02:16.930 One, two, three. 02:17.000 --> 02:17.310 Yes. 02:17.320 --> 02:21.580 So in the start here, we will write. 02:23.900 --> 02:25.730 Liveright start label. 02:25.730 --> 02:31.210 So we will move the value of value one into the Al register again. 02:31.220 --> 02:33.380 So move the Al move. 02:34.920 --> 02:35.510 Al. 02:36.390 --> 02:37.100 Fight. 02:38.390 --> 02:42.130 And value one. 02:42.140 --> 02:47.570 And as well we will move the value of value two into the Belle Register. 02:47.570 --> 02:48.890 So move. 02:49.160 --> 02:50.090 Belle. 02:52.180 --> 02:53.500 The bite again. 02:54.850 --> 02:56.080 Value to. 02:57.010 --> 03:00.530 And we will compare the values in L and l. 03:01.000 --> 03:01.410 P. 03:01.520 --> 03:03.030 L p. 03:03.130 --> 03:07.060 L, and here we will use gauge. 03:07.210 --> 03:09.750 This is a greater or equal label. 03:09.760 --> 03:13.000 So gauge here greater. 03:14.160 --> 03:15.780 Or equal. 03:15.780 --> 03:18.750 And we will develop this label right now here. 03:18.750 --> 03:19.890 So we will. 03:19.890 --> 03:29.800 In this case, we are telling the jump to greater or equal label if L is greater than or equal to b, 03:29.850 --> 03:30.390 L. 03:30.720 --> 03:39.210 So now what we're going to do is we will first, uh, generate the node grid note greater or equal label, 03:39.210 --> 03:41.850 so not greater. 03:42.780 --> 03:45.120 Or equal label. 03:45.120 --> 03:54.480 So your code I will let comment that your code here for not better or equal case and after that we will 03:54.480 --> 04:00.330 jump to down label which we will develop now GNP done. 04:00.510 --> 04:06.720 And also we will need to create the grid greater or equal when the condition met. 04:07.710 --> 04:08.550 So. 04:09.260 --> 04:10.220 Greater. 04:11.030 --> 04:12.350 Or equal. 04:12.620 --> 04:19.700 So here your code here for greater or equal case. 04:22.510 --> 04:23.830 And after that. 04:25.150 --> 04:27.790 We've all done here. 04:29.310 --> 04:29.880 Uh, this, uh. 04:29.880 --> 04:31.590 This is your exit code. 04:33.300 --> 04:33.870 Here. 04:33.870 --> 04:38.550 And also we will move racks 60. 04:38.580 --> 04:40.920 This is for fiscal number for exit. 04:42.660 --> 04:46.190 Here and xor I. 04:47.980 --> 04:48.140 The. 04:49.330 --> 04:50.940 This is the exit status. 04:50.950 --> 04:51.430 Zero. 04:51.430 --> 04:53.950 And after that, we will just call Cisco. 04:54.800 --> 05:01.880 So now I will also explain this code from beginning and in data section, we created two values. 05:02.210 --> 05:05.900 We defined the two values, the value one and value two. 05:05.990 --> 05:14.270 The both value one and value two are defined as bytes with the value of 30 and in text section here, 05:14.270 --> 05:17.780 this text section contains the main code of the program. 05:17.780 --> 05:21.620 As you know, the Start label is the entry point of the program. 05:21.620 --> 05:30.860 And here we are, we have the loading labels in the first move instruction we have here move a byte 05:30.860 --> 05:37.550 value one instruction loads the value of value one into a register. 05:37.550 --> 05:47.300 It specifies that a single byte is being loaded and similarly move B byte value two loads the value 05:47.300 --> 05:50.450 of value two into the Belle Register as well. 05:50.450 --> 05:54.780 And it also specifies that a single byte is being loaded. 05:54.780 --> 06:02.340 And in comparison, the CMP instruction compares the values in the A, L and b L register. 06:02.370 --> 06:11.610 This comparison sets various flags, including zero flag Z, F and the sign flag F, and here we have 06:11.610 --> 06:16.620 conditional jump G instruction. 06:16.620 --> 06:20.130 This instruction checks the result of the comparison. 06:20.130 --> 06:28.650 So if the sign flag is F is not set, the which is a L is greater than or equal to b, l, it jumps 06:28.650 --> 06:31.200 to greater or equal label. 06:31.200 --> 06:37.290 Otherwise it falls through to the not greater or equal label. 06:37.290 --> 06:39.150 And we have two labels here. 06:39.180 --> 06:47.760 The greater or equal label is where you can write the code that executes when value one is greater than 06:47.760 --> 06:57.660 or equal to value two and the not greater or equal here label is for writing code that executes when 06:57.660 --> 06:58.980 value one. 07:00.000 --> 07:02.970 Is not greater than or equal to value. 07:02.970 --> 07:03.360 Two. 07:03.360 --> 07:06.900 And also we have this exit code here. 07:08.190 --> 07:15.660 As you can see here in done so this program flow reaches the down label after executing the relevant 07:15.660 --> 07:18.210 code based on the comparison. 07:18.240 --> 07:28.350 The exit code is similar to previous examples using the move or racks 60 instruction for the exit syscall 07:28.350 --> 07:29.850 here and that's it. 07:29.850 --> 07:35.550 So this code demonstrates another example of using conditional branching to handle different scenarios 07:35.550 --> 07:37.590 based on the comparison result. 07:37.590 --> 07:39.660 So I'm waiting you in next lecture.
