Do you have solution for this Question. If yes    I aslo want solution.


Assume a hypothetical machine that has only PC, AC, MAR, IR, DR and Flag registers. (You may assume the roles of these registers same as that are defined in general for a von Neumann machine) The instructions of this machine can take two operands - one the operand of these must be a register operand. It has an instruction:

SUB AC, X; // it performs the operation AC ï AC – Content of location X. Write and explain the sequence of micro-operations that are required to fetch and execute the instruction. Make and state

suitable assumptions, if any
