# A new instruction is to be defined for the multiple- cycle computer. The instruction compares two unsigned

## Question:

A new instruction is to be defined for the multiple- cycle computer. The instruction compares two unsigned integers stored in register R[SA] and R[SB]. If the integers are equal, then bit 0 of R[DR] is set to 1. If R[SA] is greater than R[SB], then bit 1 of R[DR] is set to 1. Otherwise, bits 0 and 1 are both 0. All other bits of R[DR] have value 0. Find the state machine diagram for implementing the instruction, assuming that 0010001 is the opcode. Form the part of the control state table that implements this instruction.
