Simple Instructions for Arithmetic and Logical Operations
- Processors contain memory cells called registers, which are within the processor itself
- The processor has an Arithmetic Logic Unit (ALU) that performs arithmetic operations
- Information flows from registers to the ALU, then the result is stored in the accumulator
- A flag indicates the result's type (e.g., negative)
Data Transfer Instructions
- Instructions like LOAD and STORE for transferring data
- Arithmetic and Logic instructions (ADD, AND, OR, XOR, SHIFT, ROTATE)
- Control instructions (JUMP/BRANCH, HALT)
Instruction Format
- Instructions often have an opcode (operation code) and one or more operands address.
- Opcode specifies the operation to be performed (e.g., LOAD, STORE, ADD). Operands usually are address of memory locations where data is held.
Instruction Examples (LOAD, STORE).
- STORE R5, F5 stores the data from register R5 to the memory location F5
- LOAD R0, AB loads the data from memory location AB into register R0
Instructions (Examples)
- Various instructions for different operations and conditions
Jump Instructions
- Jump instructions change the program's execution flow
- Unconditional jumps: always execute the jump
- Conditional jumps: execute based on certain conditions
Jump Instructions (specific examples)
- Different jump instructions for various conditions (e.g., JC, JNC, JO, JNO, JS, JNS)
- Specific instructions for conditional jumps, such as comparisons (e.g., JGE/JNL).
