The main advantage of the RISC (Reduced Instruction Set Computer) architecture over CISC (Complex Instruction Set Computer) architecture is its higher power efficiency.
Here are the key points:
Advantages of RISC over CISC
▪
Higher power efficiency: RISC processors are designed to execute simpler instructions, which typically require fewer clock cycles and less power. This makes them more efficient in terms of power consumption
▪
Higher code density: Although RISC instructions are simpler, they can be executed more quickly and efficiently, leading to potentially higher code density in certain applications
▪
Lower cost: RISC processors are generally simpler in design, which can lead to lower manufacturing costs
▪
Compatibility with legacy code: While this is more often an advantage of CISC architectures, modern RISC processors can also include features to support legacy code, though this is not their primary advantage
In conclusion, the main advantage of RISC architecture over CISC is higher power efficiency.
