Web汇编语言中,cbw指令有何功能? 答：cbw 字节转换为字指令执行的操作：al的内容扩展到ah,形成ax中的字。al符号扩展为ax。在8086中cbw指令将al的最高有效位d7扩展至ah，即：如果al的最高有效位是0，则ah = 00，al的最高有效位为1，则ah = ffh。al不... Web11 I'm looking at this summary of the Intel x86 integer instruction set (though the same data seems to have been published in a number of places), which gives instruction timings on a per-instruction-variant basis for the Intel CPUs from 8088 to Pentium. For example, take the CBW mnenomic (opcode 98 hex):
WebOf course, multiplication is a two operand function. The 8086 always assumes the accumulator (al, ax, or eax) is the destination operand. This irregularity makes using multiplication on the 8086 a little more difficult than other instructions because one operand has to be in the accumulator. ...
