How many bits are in a byte of memory
Web32 bit and 64 bit refer to the addressable memory. A 32 bit computer can only use about 4 GB of RAM, whereas a 64 bit computer can use about 16 exabytes of RAM. 64 bit … WebTo understand the difference between byte- and word-addressable, understand that a byte is always 8 bits, while a word may differ from system to system. Take, for example, an 8-bit system with 2 byte words. The instruction size is one word, but the bandwidth of the system is only 1/2 word.

WebJan 4, 2024 · It places the higher 30 bits on the address bus, and sets all four byte-select signals, so it transfers 4 bytes. Let's get some overview: read byte from 0x1000: Address bus = 0x1000, Byte-Select 0; read byte from 0x1001: Address bus = 0x1000, Byte-Select 1; read byte from 0x1002: Address bus = 0x1000, Byte-Select 2 WebApr 9, 2024 · More precisely, the rest bits indicate the first byte of interest, and the memory reference instruction encodes the number of bytes of interest (e.g. 1, 2, 4, 8). Since the line size is 64-bytes, then the "rest" is 6 bits; these 6 bits are used after the cache lookup identifies the line (on hit).
WebFor #1, I have understood the solution as 4M = 2 2 x 2 20 = 2 22 = 22 bits. For #2 and #3, the answers provided in our lecture was: 4M X 8 bit memory requires 21 bit addresses if it is word-addressable and word size is 16 bits. 4M X 8 bit memory requires 20 bit addresses if it is word-addressable and word size is 32 bits. WebMar 14, 2024 · Since RAM is byte addressable, each cell contains exactly 1 byte. So, theoretically, we can read or write 1 byte using single memory access. But since computer has 32 bits bus, CPU always reads 32 bits using single memory access. So as far as I understand CPU reads the whole word into its register:
Webbytes (8 bytes) when aligned to byte (word) alignment. A 16 entry table is therefore 96 (128) bytes. So the space required is 1536 (2048) bytes for the top-level page table + 96 (128) bytes for one second-level page table + 1280 (2048) bytes for one third-level page table = 2912 (4224) bytes. Since the process can fit WebIn general: add 1 bit, double the number of patterns 1 bit - 2 patterns 2 bits - 4 3 bits - 8 4 bits - 16 5 bits - 32 6 bits - 64 7 bits - 128 8 bits - 256 - one byte Mathematically: n bits yields 2 …
