Web16-bit CPU with 21-bit or larger (typically 31-bit or 32-bit) total byte-addressable memory with the 1M just being a small portion of the potential addressable memory for that particular CPU. 32-bit CPU with memory addressable in 16-bit words (i.e., 1/2 the native CPU word size) for better performance with instructions that don't need 32-bit words. Web"Byte addressing" means that each byte in memory is individually addressable, i.e. there is an address x which points to that specific byte. Since there are 2^32 different numbers you can put into a 32-bit address, we can address up to 2^32 bytes, or 4 GB. It sounds like the key misconception is the meaning of "byte addressing."

WebJun 1, 2016 · They translate to the actual addressing for you i.e. work out which block to move that contains the byte you are after. The reason why bytes are chosen to be the convenient size is largely historic. It was a sensible compromise between the size of the word needed to address memory and the, possibly wasted, memory you get back.

WebHighlighting the essential difference between memory and storage, byte addressability means that a single character can be read from or written to any memory byte, whereas disks, SSDs and... WebApr 1, 2013 · The smallest addressable unit of memory is an 8-bit byte and the largest is a 32-bit word (machine word). Addresses and pointers are 32-bit as well (if we ignore segmentation and page translation). This lets us have 2 32 unique memory addresses. And, trivially, with them you can access up to 2 32 8-bit bytes of memory.

WebMIPS uses a byte- addressable memory. That is, each byte in memory has a unique address. However, for explanation purposes only, we first introduce a word-addressable memory, and afterward describe the MIPS byte-addressable memory. Figure 6.1 shows a memory array that is word-addressable. That is, each 32-bit data word has a unique 32 …

WebDec 4, 2024 · Byte addressing is hardware that allows individual bytes to be accessed from memory. The alternative, is word addressing whereby a machine only allows access to small chunks of data known as words. Words are typically 16 to 64 bits whereas a byte is 8 bits.
