Consider the 2-address instruction SUB R1, X which subtract the contents of location X from the contents of register R1 and places the result in R1. The ALU can complement either of its inputs, but it cannot subtract. Integers are stored in two’s complement representation. List the sequence of micro-operations to implement the instruction. Assume processor registers PC, MAR, MBR, IR with their usual meanings
