Question

7. What general categories of functions are specified by computer instruction?

8. In a computer, what is a bus, and what does it connect?

9. What is the maximum directly addressable memory capacity in bytes, if the address bus is 16-bit? Assume each memory location is one byte.

10. Consider a hypothetical 32-bit microprocessor having 32-bit instructions composed of two fields, the first byte contains the opcode and the remainder is the operand address.

a. What is the maximum directly addressable memory capacity in bytes? Assume each memory location is one byte.

b. How many bits are needed for the program counter and the instruction register?

Explanation / Answer

7) processor-memory, processor-I/O, data processing, and control.

8) The bus also known as the address bus, data bus, or local bus is a data connection between two or more devices(CPU, memory, etc) connected to the computer

9) maximum directly addressable memory = 216 = 64Kbytes

10)   a) The maximum directly addressable memory capacity 2 (32-8) = 16 Mbytes.

        b) 24 bits are needed for the program counter and the instruction register needs 32 bits.
