Question
Design the logic to control an ALU, which has the following inputs: Ainvert,Binvert,Cin,Op1 (high bit of the 2-bit operation input),Op0 (low bit of the 2-bit
Design the logic to control an ALU, which has the following inputs:
Ainvert,Binvert,Cin,Op1 (high bit of the 2-bit operation input),Op0 (low bit of the 2-bit operation input)
Assume that you only need to design ALU control circuitry for these six R-type instructions: add, and, nor, or, sub, slt.
a. The MIPS encoding for each of these six instructions has an opcode of 0; however, each has a different function code.
b.rovide the truth table that describes the ALU's control logic. There are exactly six inputs the six bits of the function code (in order). Label them F5 ... F0. There are exactly five outputs the five ALU inputs listed above.
c. Provide the Boolean algebra expression for output Binvert only. Use the truth table and sum of products to arrive at your answer.
