D. MIPS

Right Answer is: B
SOLUTION
- IBM was the first company that defined RISC architecture in 1970.
- RISC (Reduced Instruction Set Computer) is a microprocessor that is designed to perform a 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.
- RISC is implemented using the 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:
1) RISC instruction set are simple and of fix size.
2) Fewer instructions in RISC.
3) High performance
4) Simple addressing modes
5) Large number of registers.
