processor instruction sets Flashcards
1
Q
What is an instruction set?
A
complete set from entire code that can be recognised and executed by a CPU
they are libraries of all things the processor can be asked to do
2
Q
Explain RISC
A
reduced instruction set computer
can process a limited number of relatively simple instructions
advantages= processes simple instructions quicker/ less power consumption/ less heat generated
3
Q
Explain CISC
A
processes large number of complex instructions
advantage= complex instructions don’t have to be broken down
disadvantages= more power consumption/ more heat produced/ more circuitry to decode and execute instructions
