Chapter 5, Problem 11RETC

Explanation of Solution

Types of instructions:

Data movement:

Data movement instructions are used most frequently. With the use of these instructions, data is moved from memory into registers, from registers to registers, and from registers to memory, and many machines also provide different instructions depending on the source and destination. These instructions include MOVE, LOAD, STORE, PUSH, POP, EXCHANGE and various variations on each of these.

Arithmetic operations:

The instructions that use integers and floating-point numbers are categorized as arithmetic operations. Many instruction sets provide different arithmetic instructions for various data sizes. These instructions also provide different instructions for different combinations of register and memory accesses in different addressing modes. These instructions include ADD, SUBTRACT, MULTIPLY, DIVIDE, INCREMENT, DECREMENT, and NEGATE.

Boolean logic instructions:

These instructions perform operations which work similar to that of arithmetic operations. Logic operations are used to control input/output devices. As with arithmetic operations, logic operations affect the flag register. These instructions include AND, NOT, OR, XOR, TEST, and COMPARE.

Bit manipulation instructions:

These instructions are used to set and reset individual bits within a given word...
