1 00:00:00,060 --> 00:00:04,140 So before we proceed to understand how we access the data from a beta. 2 00:00:04,290 --> 00:00:09,510 OK, so let me just try to discuss some of the phenomena related to memory that help us to understand 3 00:00:09,900 --> 00:00:12,480 what we mean when we see byte addressable memory. 4 00:00:13,050 --> 00:00:16,910 So when we consider the memory there is, do we have a memory like this, right? 5 00:00:16,920 --> 00:00:24,810 So we have a multiple locations where we could see see the diary, for example, if memory is of SAYISI, 6 00:00:24,810 --> 00:00:33,120 but right and it have unique 64 locations, unique 64 location basically mean we have a 64 addresses 7 00:00:33,120 --> 00:00:35,250 where we could to it, right? 8 00:00:35,490 --> 00:00:39,060 So we can see that our memory looks something like this, right? 9 00:00:39,070 --> 00:00:41,280 So we have. 10 00:00:42,510 --> 00:00:44,780 So capacity to store it. 11 00:00:45,300 --> 00:00:45,660 OK. 12 00:00:46,140 --> 00:00:51,020 With each location and each location will have a unique address. 13 00:00:51,240 --> 00:00:56,730 So we have 60 votes each location, so our address will be from zero to 60. 14 00:00:57,030 --> 00:00:57,270 Right. 15 00:00:57,480 --> 00:01:00,360 And each address will store it right. 16 00:01:00,390 --> 00:01:01,200 This makes sense. 17 00:01:01,950 --> 00:01:06,210 Now, when we consider the memory, so this is referred to as a rate. 18 00:01:06,240 --> 00:01:12,720 So each data, the unique data that you give stool at a specific location, OK in a memory is referred 19 00:01:12,720 --> 00:01:13,890 to as a set, right? 20 00:01:14,190 --> 00:01:18,450 So if you have a set of size and then depending on the. 21 00:01:19,630 --> 00:01:20,650 Address space. 22 00:01:20,690 --> 00:01:27,220 OK, so we have that many locations that are available very close to the right, and this defines the 23 00:01:27,220 --> 00:01:28,440 size of a memory. 24 00:01:28,450 --> 00:01:33,910 So this we often refer to as 64 seat bit of memory. 25 00:01:33,970 --> 00:01:42,530 Right now, memory could be categorized into two different these souki in the way we access Azita, 26 00:01:42,610 --> 00:01:46,210 so it could either be the white addressable memory. 27 00:01:46,840 --> 00:01:47,200 OK. 28 00:01:47,500 --> 00:01:52,090 And the second one is the word addressable memory. 29 00:01:52,300 --> 00:01:57,190 So these are the two ways by which we access the data from a memory. 30 00:01:57,270 --> 00:01:57,490 Right? 31 00:01:58,000 --> 00:02:04,300 So when we continue to bite in this economy, the simple fact you know about this is when we see byte. 32 00:02:05,930 --> 00:02:13,850 So this signifies that each bite rate, each bite will have. 33 00:02:14,820 --> 00:02:15,990 Unique address. 34 00:02:17,080 --> 00:02:17,290 Right. 35 00:02:17,770 --> 00:02:25,390 Similarly, if you work on the seam line, so would addressable basically mean each word? 36 00:02:26,500 --> 00:02:28,330 We'll have. 37 00:02:29,460 --> 00:02:33,660 Unique address right now, what we really mean. 38 00:02:35,720 --> 00:02:42,860 So the definition of work depends primarily on the architecture that you are referring to, for example, 39 00:02:43,130 --> 00:02:49,490 world may have completely different meaning if you consider 16 bit prosit as compared to 32 bit processor, 40 00:02:49,490 --> 00:02:49,680 right? 41 00:02:49,710 --> 00:02:53,210 So that is a do you have a 64 bit processor, right? 42 00:02:53,390 --> 00:02:58,970 So in that processor, OK, or in that CPU, we could see that the word size? 43 00:02:59,000 --> 00:03:00,950 OK, world sizes 16. 44 00:03:01,280 --> 00:03:07,750 But in that case, also bite size will remain seem to bite size will always need independent off with 45 00:03:07,770 --> 00:03:09,350 architecture that we are utilizing. 46 00:03:09,530 --> 00:03:10,460 So this we already know. 47 00:03:10,460 --> 00:03:12,110 So it is referred to as invite. 48 00:03:12,380 --> 00:03:17,780 So that won't be changing between CPU architecture, but something that changes the world. 49 00:03:18,050 --> 00:03:21,140 So if you have 16 bit CPU, world size will be 16. 50 00:03:21,380 --> 00:03:29,240 If you have 32 bit CPU, OK, then in that case, world size OK will be 32 bit right. 51 00:03:29,450 --> 00:03:36,890 Similarly, if you have a 64 bit CPU, OK, in that case, the world size world size will be 64. 52 00:03:36,990 --> 00:03:37,250 Right? 53 00:03:37,430 --> 00:03:40,820 And this world size represent the single leader transaction. 54 00:03:41,090 --> 00:03:46,390 So remember this thing, depending on the CPU architecture that you are utilizing, were size me. 55 00:03:46,880 --> 00:03:47,210 OK? 56 00:03:47,840 --> 00:03:53,380 So far, use of 16 bit it will be 16 again for use of 32 bit CPU. 57 00:03:53,390 --> 00:03:54,640 It will be thirty nine. 58 00:03:54,680 --> 00:03:59,120 This represent the single data transaction for that specific kind of a. 59 00:03:59,510 --> 00:03:59,780 Right. 60 00:03:59,990 --> 00:04:06,380 So when we consider lyricism, byte addressable memory rates, we know each byte will have a unique 61 00:04:06,380 --> 00:04:06,950 address rate. 62 00:04:06,950 --> 00:04:10,860 So if we just wish to draw the memory for this game? 63 00:04:10,970 --> 00:04:11,210 Right. 64 00:04:11,210 --> 00:04:12,590 So in that case, there is a do. 65 00:04:12,610 --> 00:04:15,260 We have a multiple unique sense, right? 66 00:04:15,860 --> 00:04:18,580 So each cell will have a unique address. 67 00:04:18,840 --> 00:04:26,810 So here now if you consider a byte addressable memory, so let's assume you have a 64 unique location 68 00:04:26,840 --> 00:04:28,360 where we could store it. 69 00:04:28,370 --> 00:04:33,830 Bit of right to each cell in this kind of memory is capable of storing it right. 70 00:04:34,050 --> 00:04:38,510 So such kind of memory is referred to as divided residual memory. 71 00:04:38,740 --> 00:04:38,810 Right. 72 00:04:39,080 --> 00:04:46,990 When we consider the word addressable memory, let us assume again we have a 60 for unique location, 73 00:04:47,000 --> 00:04:47,320 right? 74 00:04:47,340 --> 00:04:55,640 So here we will be having an address ranging from zero to sixty three and each address now or each cell 75 00:04:55,640 --> 00:04:58,790 is capable of storing it right. 76 00:04:58,970 --> 00:05:00,530 So here we have a word zero. 77 00:05:01,680 --> 00:05:02,400 Word one. 78 00:05:02,670 --> 00:05:08,400 And then word six to three right now, word size will be varying depending on the CPU architecture that 79 00:05:08,400 --> 00:05:09,510 you are targeting, Rachel. 80 00:05:09,690 --> 00:05:11,820 This is what we refer to as the. 81 00:05:13,140 --> 00:05:16,680 World oriented memory or word addressable memory. 82 00:05:16,890 --> 00:05:19,950 So this is the primary difference that we have between. 83 00:05:21,140 --> 00:05:25,610 The byte addressable memory and the word addressable memory, right, so you could really understand 84 00:05:25,610 --> 00:05:29,480 now that when we consider the byte addressable memory, right? 85 00:05:29,510 --> 00:05:34,880 So in that GIS, each byte, it would basically represent a single byte. 86 00:05:35,060 --> 00:05:37,270 So each byte have a unique address. 87 00:05:38,450 --> 00:05:44,150 And when we consider world addressable right to each word, have a unique address right now when we 88 00:05:44,150 --> 00:05:45,510 consider our microplates. 89 00:05:45,870 --> 00:05:52,220 So when we consider now micro, please, so micro please is having a 32 bit of it, right? 90 00:05:52,220 --> 00:05:56,110 So it is basically having a word size of 32 bit, right? 91 00:05:56,690 --> 00:05:59,570 Similarly, the transaction is of, say, 32 bit. 92 00:05:59,810 --> 00:06:06,560 But the type of memory that my group is utilized is the byte addressable memory. 93 00:06:08,040 --> 00:06:08,360 OK. 94 00:06:08,670 --> 00:06:13,140 And this basically be a bit of confusion because. 95 00:06:14,770 --> 00:06:21,790 So, ladies, do we want to perform a single detransition lecture here addressing the memory is a bit 96 00:06:21,790 --> 00:06:22,600 confusing, right? 97 00:06:22,900 --> 00:06:26,090 So let us do we have words, the right words? 98 00:06:26,110 --> 00:06:28,810 It'll have an address of CO2, right? 99 00:06:29,080 --> 00:06:34,750 We already know that our memories and our detour sizes of 32 bit, right? 100 00:06:34,990 --> 00:06:39,740 So you have our first bite look at at this second bite. 101 00:06:39,760 --> 00:06:41,910 Look, we delivered this one third bite. 102 00:06:41,920 --> 00:06:45,000 Look into this too and would bite. 103 00:06:45,010 --> 00:06:47,000 Look at it, an address for the right. 104 00:06:47,800 --> 00:06:57,910 So we at news request for addresses to correctly stool single data transaction, record single data 105 00:06:58,180 --> 00:06:59,020 into a memory. 106 00:06:59,170 --> 00:07:03,580 So this ultimately suggests that when we want to access the next word. 107 00:07:03,640 --> 00:07:03,970 Right? 108 00:07:04,150 --> 00:07:07,730 So the address should be automatically secured by food. 109 00:07:07,780 --> 00:07:08,050 Right. 110 00:07:08,260 --> 00:07:13,350 Because our next data would only be stored at an address of food. 111 00:07:13,390 --> 00:07:13,660 Right. 112 00:07:13,690 --> 00:07:18,800 Similarly, this is also why do we need to go to seven to store? 113 00:07:18,820 --> 00:07:19,930 All right. 114 00:07:20,170 --> 00:07:21,850 So when we consider micro, please. 115 00:07:22,060 --> 00:07:25,930 OK, so if you can see the memory and if you want to access the memory. 116 00:07:26,170 --> 00:07:29,900 So this is the memory that we have for our listeners who might replace this. 117 00:07:29,900 --> 00:07:34,330 So we have some unique locations from zero x and each word. 118 00:07:34,330 --> 00:07:37,300 When we consider the decision, this is what zero. 119 00:07:37,630 --> 00:07:46,180 So the next location or the next word will be automatically located at Dressel because we have a buy 120 00:07:46,180 --> 00:07:47,110 to the Indian memory. 121 00:07:47,560 --> 00:07:52,350 So to store a single 32 bit data, be required for addresses. 122 00:07:52,570 --> 00:07:58,840 So the next address or the next D next word will be automatically stored. 123 00:08:00,020 --> 00:08:01,610 We buy food location, right? 124 00:08:01,790 --> 00:08:08,000 Similarly, if you want to access the next it, it will be automatically operated by four, right? 125 00:08:08,010 --> 00:08:13,310 So if you consider it with the first word, so it will be having an accurate selfie. 126 00:08:13,580 --> 00:08:17,570 And if you consider this the word one, it will be operated by four. 127 00:08:17,610 --> 00:08:17,780 Right. 128 00:08:17,810 --> 00:08:20,110 So this is how we will be addressing Adidas.
