Points) 512 2 1. A computer system uses a memory unit of 512K words of 32 bits each. A binary instruction code is stored in one word of memory. The instruction has three parts; an indirect bit, an operation code, and an address part. a. How many bits are there in the operation code and the address part of the instruction code? (5 Points) Opcode: Address: b. How many bits are there in the data and address inputs of the memory? (5 Points) Address input: Data input: 2. The content of PC in the computer is B20 (all numbers are in hexadecimal). The content of AC is ACEO. The content of memory address at address B20 is 845E. The content of memory at address 45E is 0C9A. The content of memory at address C9A is 7AB7. a. What is the instruction that will be fetched and executed next? (5 Points) b. Show the binary operation that will be performed in the AC when the instruction is executed? (5 Points) c. Give the contents of registers PC, AR, DR, AC, and IR in hexadecimal at the end of the instruction cycle. (Show Your Work) (10 Points)
