RISC stands for ___________

Concept:

RISC (reduced instruction set computer) is a microprocessor that is designed to perform smaller number of instructions so that it can operate faster. RISC instruction sets are simple. RISC instruction takes only one clock cycle per instruction to execute.

Explanation:

RISC is implemented using hardwire control unit. RISC uses registers instead of memory. Registers are small in size and are on the same chip on which ALU and control unit are present. RISC architecture is shown below.

Feature of RISC processor are:

• RISC instruction sets are simple and of fixed size.
• Fewer instructions in RISC.
• High performance
• Simple addressing modes
• A large number of registers.
• Instruction come undersize of one word.
