Question: For the following, we consider instruction encoding for instruction set architectures. a. Consider the case of a processor with an instruction length of 14 bits

For the following, we consider instruction encoding for instruction set architectures.

a. Consider the case of a processor with an instruction length of 14 bits and with 64 general-purpose registers so the size of the address fields is 6 bits. Is it possible to have instruction encodings for the following?

■ 3 two-address instructions

■ 63 one-address instructions

■ 45 zero-address instructions

b. Assuming the same instruction length and address field sizes as above, determine if it is possible to have

■ 3 two-address instructions

■ 65 one-address instructions

■ 35 zero-address instructions Explain your answer.

c. Assume the same instruction length and address field sizes as above. Further assume there are already 3 two-address and 24 zero-address instructions. What is the maximum number of one-address instructions that can be encoded for this processor?

d. Assume the same instruction length and address field sizes as above. Further assume there are already 3 two-address and 65 zero-address instructions. What is the maximum number of one-address instructions that can be encoded for this processor?
