What is ALU?
| Arithmetic Logic Unit |
|
The section of a computer, processor, or microprocessor that deals with the decision making process that separates calculators from computers. In the early days of computers, the ALU was an entire board, often referred to as the logic board. Designers eventually worked the size down enough to become a daughter board to the CPU card. Since early into 8 bit microprocessors, the ALU has been an integrated part of the CPU chip itself. The decision making process deals with Boolean functions and the typical greater than or less than, equal or not equal calls from higher level programs. |
