P1. Consider a hypothetical 32-bit microprocessor having 32-bit instructions composed of two fields: the first byte contains the opcode, and the remainder the immediate operand or an operand address. a. What is the maximum directly addressable memory capacity, in Mbytes? b. Discuss the number of bus cycles needed to transmit memory addresses and data if the microprocessor bus has 1. a 32-bit local address bus and a 16-bit local data bus, or 2. a 16-bit local address bus and a 16-bit local data bus
