A. A memory unit has a capacity of 65,536 words of 25 bits each. It is used in conjunction with a general-purpose computer. The instruction code is divided into four parts, an operation code, an indirect mode (1 bit), a register field (2 bits) and an address field (for all direct memory references). (i) Draw the instruction word format indicating the number of bits and the function of each part. (ii) What is the maximum number of operations that can be incorporated in the computer if an instruction is stored in one memory word? (iii) How many processor registers are there in the computer and how many bits in each? (iv) How many bits are there in the MBR, MAR and PC? 4 Marks A.
