What instructions does RISC have?
RISC is an abbreviation of Reduced Instruction Set Computer. RISC processor has ‘instruction sets’ that are simple and have simple ‘addressing modes’. A RISC style instruction engages “one word” in memory. Execution of the RISC instructions are faster and take one clock cycle per instruction.
What is nature of instruction in RISC processor?
