Risc Vs Cisc

Question 1

What does CISC aim to do?

Answer 1

Execute a task in as few lines of code as possible and take stress off the compiler/interpreter

Question 2

Where is CISC found?

Answer 2

Mainly in desktop PCs and laptops

Question 3

What does RISC aim to do?

Answer 3

Use simple instructions that can execute in one clock cycle each

Question 4

What are the advantages of RISC?

Answer 4

RISC instructions require less complex hardware and less transistors, so there is more room for RAM and Cache
Pipelining is possible
Less energy is required
Cheaper

Question 5

What are the advantages of CISC?

Answer 5

Less compiler work is required to convert high level code into assembly
More cycles per second
Makes better use of RAM

Question 6

Where is RISC used?

Answer 6

Low power, portable devices (smart watches, thermostats, phones, printers etc)
Risk makes up >90% of processors
