The Arithmetic Logic Unit (ALU) is a digital circuit within a CPU that performs arithmetic and logical operations on binary data.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Latency | Typically 1-5 clock cycles per operation | |
| Bit Width | 32-bit, 64-bit, or other architectures | |
| Clock Speed | GHz range (dependent on CPU design) | |
| Operation Types | Integer arithmetic, floating-point arithmetic, logical operations | |
| Technology Node | e.g., 7nm, 5nm (semiconductor fabrication process) | |
| Power Consumption | Milliwatts to watts (varies with design and process) |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
The computational core of a PLC controller that executes control logic and processes input/output signals.
The primary computational and control unit within a processor that executes instructions and manages data flow.
Integrated circuit that processes digital signals and controls functions within signal transmitters and converters

Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
The ALU performs all arithmetic and logical calculations required by a CPU, such as adding numbers or comparing values.
Unlike the control unit (which directs operations) or cache (which stores data), the ALU is specifically designed for computation tasks.
Yes, modern ALUs often include or are paired with a Floating-Point Unit (FPU) to handle non-integer calculations efficiently.
