A computer uses a memory unit with 256k words of 32 bits each. A bina. ry instruction code is stored in one word oi memory. The instruction has four
parts: an indirect bit. an operation code, a registu code part to specify one
of 64 registers, and an address part.
a. How many bits are there in the operation code, the register code part,
and the address part?
b. Draw the instruction word format and indicate the numberolbits in each
part.
c. How many bits are there in the data and address inputs oi the memory?
