CSC 3351 Operating Systems Test 1 (03/03/2000) (150 points) 1. Multiple choice questions : Circle the best match (40 points) Q1. Consider a microprocesssor with a 20-bit address bus and a 24-bit data bus. The microprocessor is connected to a “32-bit memory” (i.e., unit of storage is 32 bits). Then the maximum addressable space is : A. 4.2 24 B.2 20 C. 2 24 D. 2.2 20 E.None Q2. Consider a microprocesssor with a 20-bit address bus and a 24-bit data bus. The microprocessor is connected to a “32-bit memory” (i.e., unit of storage is 32 bits). Then the maximum addressable memory capacity is (in bytes): A. 4.2 24 B.2 20 C. 2 24 D. 2.2 20 E.None Q3. Consider a microprocesssor with a 20-bit address bus and a 24-bit data bus. The microprocessor is connected to a “32-bit memory” (i.e., unit of storage is 32 bits). Its program counter has 32 bits. The instruction format reserves 12 bits for the opcode and 20 bits for a memory operand address. This microprocessor may have up to _______ different instructions : A. 2 20 B.2 12 C. 2 24 D. 2.2 20 E.None Q4. Consider a microprocesssor with a 20-bit address bus and a 24-bit data bus. The microprocessor is connected to a “32-bit memory” (i.e., unit of storage is 32 bits). Its program counter has 32 bits. The instruction format reserves 12 bits for the opcode and 20 bits for a memory operand address. An instruction can access a maximum addressable space of :
