Suppose the processor is modified such that it can is 21-bit processor and can address 2^16 Memory locations:

What is the word size?

How that will affect the size of ALU and internal registers including PC, AC, MAR and MBR?

Draw a general model for the computer system showing how memory and CPU interact with each other. Show the necessary buses and signals that can be used for the communication between CPU and Memory, according to Von Neumann’s architecture, and the width of each one.

How many instructions that this processor can support.

Solution

1)Word size is 24 bits for the 21 bit processor .

2)Size of ALU,PC,AC,MAR and MBR : is same as the number of bits of the processor 21 bits.

3) 65536 are the number of instructions this processor can support.
