(c)
A computer uses a memory unit with 256K words of 32 bits each. A binary instruction code is stored in one word of memory. The instruction has four parts: an indirect bit, an operation code, a register code part to specify one of 64 registers, and an address part.
1How many bits are there in operation code, the register code part and the address part?
2Draw the instruction word format and indicate the number of bits in each part.
3How many bits are there in the data and address inputs of the memory?
