1.1.2- CISC and RISC Flashcards
Advantage of RISC
Cheaper
Programmes run faster due to simpler instructions
Features of RISC
Instructions are a fixed length
Can use pipelining
Used in embedded systems (smartphones, tablets)
Uses more RAM
Used in everyday devices
RISC
Reduced instruction set computer
Aims to use simplistic instructions that will be executed within a single clock cycle
CISC
complex instruction set computer
General purpose register used in laptops and desktops
Aims to complete tasks in as few lines of assembly as possible
Features of CISC
Large instruction set
Instructions built into hardware
Used in embedded systems and microprocessors
Benefit of RISC
pipelining possible because each instruction takes one clock cycle
