Web7 sep. 2024 · 2.3: Memory Maps. Every byte of memory in a computer system has an address associated with it. This is a requirement. Without an address, the processor has no way of identifying a specific location in memory. Generally, memory addressing starts at 0 and works its way up, although some addresses may be special or “reserved” in some … Web4 nov. 2024 · In memory-mapped I/O, both memory and I/O devices use the same address space. We assign some of the memory addresses to I/O devices. The CPU treats I/O devices like computer memory. The CPU either communicates with computer memory or some I/O devices depending on the address.
