What we have learnt
- The CPU consists of various components including ALU, registers, and control units, each serving specific functions.
- Registers are classified into general-purpose and specialized types, crucial for executing instructions and holding data.
- Altering design choices in ALU architecture affects performance and cost, and the bus system allows efficient component interconnectivity.
Key Concepts
- -- Arithmetic Logic Unit (ALU)
- The component of the CPU responsible for performing arithmetic and logic operations on data.
- -- Registers
- Small storage locations within the CPU used to hold data and instructions temporarily during processing.
- -- Bus Architecture
- A communication system that transfers data between components of a CPU and peripheral devices.
- -- Control Signals
- Signals generated by the control unit to manage the operations of the CPU components.
