1 00:00:04,460 --> 00:00:09,850 In the piece video, we discussed the hardware part of that video system here, we discussed the features 2 00:00:09,860 --> 00:00:13,690 of it and video systems that led to the future in the Amber Alert system. 3 00:00:14,000 --> 00:00:20,990 The first feature is that it did a single function unit that it perform, some dedicated to some single 4 00:00:20,990 --> 00:00:24,900 task is that it executed a single program repeatedly. 5 00:00:25,310 --> 00:00:32,840 So far in the programming we use, Wildeman functions that can perform this in the program repeatedly. 6 00:00:33,410 --> 00:00:36,230 Next, it is time constraints. 7 00:00:36,590 --> 00:00:40,430 That article, titled Constraints are posted low cost. 8 00:00:40,920 --> 00:00:47,390 We want to make the application the low cost in the loop, our accountability system, opportunity systems. 9 00:00:47,570 --> 00:00:48,980 So really quite low power. 10 00:00:49,610 --> 00:00:56,870 The applications are small inside and they do the operation fast, so we require the fast operation 11 00:00:56,870 --> 00:00:58,940 in that system next. 12 00:00:58,940 --> 00:01:01,190 Tightly constrained is life. 13 00:01:01,190 --> 00:01:11,660 Treating stage 24 seven 365 means that it work in the 24 hours, seven days and 365 days, 24 hours, 14 00:01:11,660 --> 00:01:13,200 seven days, 365 days. 15 00:01:13,700 --> 00:01:17,680 So these are some tightly constraints of the Amber Alert system connected. 16 00:01:17,880 --> 00:01:24,550 It is ineffective and the to means that it form the task and then real time means that it continuously 17 00:01:24,810 --> 00:01:27,260 could change in the systems environment. 18 00:01:27,560 --> 00:01:28,670 And so you can use that. 19 00:01:29,000 --> 00:01:35,720 It must compute certainly in real time without delay means that it perform the task in realtime. 20 00:01:35,990 --> 00:01:41,930 They are two type of realtime systems, Westchester's of real time, systematic and is the hard realtime 21 00:01:41,930 --> 00:01:45,950 system in the software type systems that time. 22 00:01:46,130 --> 00:01:54,200 It's something that if we want to make a task and the task is completed in ten minute or one second, 23 00:01:54,620 --> 00:02:00,370 that one second can be change, it can be up or down that it is the software system. 24 00:02:00,650 --> 00:02:07,250 And if we want to do the task in time, ten minutes and it must complete the timer, then it is that 25 00:02:07,250 --> 00:02:08,420 hardware time system. 26 00:02:08,600 --> 00:02:14,740 So they are put dybbuk, the alarm system, software and hardware system. 27 00:02:14,960 --> 00:02:17,570 So these are the features of an amber.
