COMPUTER ORGANIZATION & ARCHITECTURE(3). 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 bytes)? (b) Discuss the impact on the system speed if the microprocessor bus has— i) a 32-bit local address bus and a 16-bit local data bus, or ii) a 16-bit local address bus and a 16-bit local data bus. \(c\) How many bits are needed for the program counter and the instruction register?202214mCOMPUTER ORGANIZATION & ARCHITECTUREA computer has 16 registers, an ALU with 32 operations, and a shifter with 8 operations, all connected to a common bus system.
