Question

An ISA specifies a word size of 8 bytes; word addressability, and an address space of 4G; it uses single-word instructions (i.e. each instruction is a single 8 byte word). What are the sizes of the PC and the IR? both 24 bits PC: 24 bits; IR:64 bits both 32 bits 64 bits; IR:32 bits both 64 bits PC: 32 bits; IR:64 bits For the system in the previous question: What are the sizes of the MDR and the MAR? both 24 bits MAR: 32 bits; MDR: 64 bits both 32 bits MAR: 64 bits; MDR: 32 bits both 64 bits MAR: 24 bits; MDR: 64 bits
