When a new processor is designed the instruction set must be finalised first. A new processor with a 32-bit word length is being developed for use in a mobile phone a. It has been decided that the processor will use 60 different instructions . How many bits should be used for the opcode? [1 mark] b. If there are two bits available for the addressing mode, what is the maximum value that can be used for the operand ? (Show your working .) [3 marks ] C. How much memory, in MiB, can the processor work with, assuming one address references one word of data? (Show your working .) [3 marks ]
