What is RISC?
| Reduced Instruction Set Computing |
|
A type of microprocessor design that focuses on rapid and efficient processing of a relatively small set of instructions. RISC design is based on the premise that most of the instructions a computer carries out are simple instructions. As a result, Reduced Instruction Set Computing architecture limits the number of instructions that are built into the microprocessor but optimizes each so that it can be carried out very quickly. RISC microprocessors carry out simple tasks faster than CISC (Complex Instruction Set Computing) microprocessors but are slower with complex instructions which must be broken down before they can be carried out by the RISC chips. |
