This despite the 8088 coming in two versions - 5 MHz and 8 MHz. Since later PC's routinely operated at higher clock speeds and typically up to the CPU's spec, I assume some cost … Web30 de set. de 2013 · 1. On a 8-bit CPU you compare the first (= highest) byte. If it is equal you compare the second (= lower) byte. When comparing 32- or 64-bit numbers you …

Web13 de jan. de 2015 · This info is quite outdated. On a new CPU a mul reg,reg is almost always faster than shifts and adds. Esp. because shifts and adds lengthen the dependency chain. Also x86 has a barrel shifter. shr eax,3 happens in a single cycle and can be paired with 3 other instructions for a 1/4 of a cycle cost. There is no need to create a long … Web2) Data bus of 8086.
