Difference between RISC and SISC architecture in CPU's (Central Processing Units)
RISC vs. CISC: A Comparative Analysis RISC (Reduced Instruction Set Computer) and CISC (Complex Instruction Set Computer) are two primary architectural approaches used in computer processors. They differ significantly in their design philosophies and performance characteristics. ARM (like Apple M series and Qualcomm Snapdragon) adopts a RISC (Reduced Instruction Set Computing) philosophy, whereas x86 (like Intel and AMD) is based on a CISC (Complex Instruction Set Computing) approach. These divergent strategies influence the efficiency and performance of processors and their application in various computing environments. RISC Architecture Emphasis on software: RISC relies heavily on software optimization to achieve high performance. Simple instruction set: A limited number of simple, fixed-length instructions. Single-cycle execution: Most instructions can be executed in a single clock cycle. Large number of registers: More registers reduce memory access and improve performance. ...
