Complex Instruction Set Computer

Question 3

What are the 3 properties of RISC?

Answer 3

1. Small instruction set
2. Each instruction is one line of machine code
3. Used in everyday devices

Question 4

What are the 3 properties of CISC?

Answer 4

1. A large instruction set
2. Instructions are built into hardware
3. Used in embedded systems and microprocessors

Question 5

What are the benefits of RISC processors?

Answer 5

1. Pipelining is possible as instructions take one clock cycle

Question 6

What are the benefits of CISC processors?

Answer 6

1. Compilers have to do less work
2. They require less RAM because instructions are smaller

Question 7

What is GPU?

Answer 7

Graphics processing unit is a co-processor made up of lots of independent parallel processors.

Question 8

What are GPU’s used for now?

Answer 8

Image processing and machine learning

Question 9

What is a multi-core processor?

Answer 9

Systems where there are multiple cores with separate fetch-decode-execute cycles.

Question 10

What are parallel systems?

Answer 10

Systems where multiple instructions can be completed at a given time. It could through threading or pipelining.
