Question 2 Design a very simple CPU that can access 64 bytes of memory, each byte being 8 bits wide. The CPU must do it by outputting a 6-bit address on its output pins A[5...0] and reading in the 8 bit value from memory on its inputs D[7...0]. The CPU will have only one programmer accessible register, an 8-bit accumulator labelled AC. The CPU has only 4 Instructions in its Instruction set as follows: Instruction ADD AND JMP INC Instruction Set for the Very Simple CPU. Instruction Code 00AAAAAA 01AAAAAA 10AAAAAA 11XXXXXX Operation AC AC+M[AAAAAA] AC AC M[AAAAAA] GOTO AAAAAA AC AC+1 Answer the following question: Give reasons, why this is a fairly impractical CPU?
