Explain Risc Architecture?
Answers
Answer:
A reduced instruction set computer (RISC) is a computer that uses a central processing unit (CPU) that implements the processor design principle of simplified instructions. To date, RISC is the most efficient CPU architecture technology.
hello mate here is your answer
=>
RISC meaning reduced instruction set as the acronym say aims to reduce the execution times of instructions by simplifying the instructions. The major characteristics of RISC are as follows:
- Compared to normal instructions they have a lower number of instructions.
- The addressing modes in case of RISC is also lower.
- All the operations that are required to be performed take place within the CPU.
- All instruction are executed in a single cycle hence have a faster execution time.
- in this architecture the processors have a large number of registers and a much more efficient instruction pipeline.
- Also the instruction formats are of fixed length and can be easily decoded.
Hope it's correct pls mark as branlist!!!!!!
