[Solved] Worst case memory access in 80×86 assembly
[ad_1] From memory, the instruction has an opcode byte (“add”), an address mode byte, an offset for x (4 bytes) and the constant (4 bytes) ==> 10 bytes. I assume the 486 fetches 4 bytes at a time from memory with a bus address aligned to 4 byte DWORD boundaries. So 10 bytes arguably takes … Read more
