Consider a hypothetical microprocessor having 32-bit instructions composed of two fields: the first Byte contains the opcode and the remainder the immediate operand or operand address. What is the maximum directly accessible memory capacity (in Bytes)? Discuss the impact on the system speed if the microprocessor bus has: a 32-bit local address bus and a 16-bit local data bus a 16-bit local address bus and a 16-bit local data bus
