Web16 sep. 2024 · Well, Z-80 memory access is fastest through the PUSH and POP instructions. PUSH can write 2 bytes in 11 cycles and POP can read 2 bytes in 10 cycles. Thus the theoretical maximum speed write is 5.5 cycles/byte and maximum speed read is 5 cycles/byte. This means that 10.5 cycles/byte is the best we could possibly do.
