Use two words to represent the move instruction of problem 6. The first word contains the opcode, address modifiers, and the address of A, and the second word contains the address modifiers and the address of B (the opcode field in this word is not used). Write the microprogram.

Problem 6:

Write the microprogram to implement the following move multiple words instruction:

MOV A, B

which moves N words from memory locations starting at A to those at B. The value of N is specified in the accumulator. Assume that A and B are represented as 4-bit fields in the 8-bit operand field of the instruction, and indexing and indirecting are not allowed. What is the imitation of this instruction?
