Study Notes
Arithmetic Logic Unit (ALU)
- The primary function of an Arithmetic Logic Unit (ALU) is to perform arithmetic and logical operations, such as addition, subtraction, AND, OR, and NOT.
Operations of ALU
- A simple ALU can perform basic arithmetic operations like addition, subtraction, multiplication, and division.
- It can also perform logical operations like AND, OR, NOT, and XOR.
Design Specifications of ALU
- The design specifications of an ALU are derived from the Instruction Set Architecture (ISA) of the computer.
Purpose of Co-processor
- The purpose of a co-processor in relation to ALU is to offload specific tasks, such as floating-point operations, from the main ALU, thereby increasing the overall processing speed.
Multiple ALUs in Modern CPUs
- Modern CPUs have multiple ALUs to increase processing speed and efficiency by performing multiple operations simultaneously.
- This allows for better parallel processing, pipelining, and multitasking capabilities.
