A digital computer has a memory unit with 49 bits per word. The instruction set consists of 312 different operations. All instructions have an operation code part (opcode) and two address fields: one for a memory address and one for a register address. This system includes 32 registers.

a) How many bits are needed for the opcode?

b) How many bits are needed to specify the register?

c) How many bits are left for the memory address part of the instruction?

d) What is the maximum allowable size for memory?

e) What is the largest unsigned binary number that can be accommodated in one word of memory?
