Web9 jul. 2024 · In reality, memory is only byte addressable. It means: A binary address always points to a single byte only. A word is just a group of bytes – 2, 4, 8 depending upon the data bus size of the CPU. To understand the memory operation fully, you must be familiar with the various registers of the CPU and the memory ports of the RAM. WebARM processors normally have 32-bit wide address buses. A 32-bit ARM processor could address up to 2 32 = 4,294,967,296 memory locations! In older computers, the data bus was a mere 8 bits wide ( d =8). Each location was an 8-bit byte. Each byte (8 bits) could store either an unsigned number in the range 0-255 or a 2's-complement signed number ... WebByte addressability enables even a single numeric digit to be calculated, compared and copied independently of the data residing in the bytes next to it. Contrast with block addressable.
