1.1.2. Types of Processor

Question 1

What does RISC stand for?

Answer 1

reduced instruction set computer

Question 2

What does CISC stand for?

Answer 2

complex instruction set computer

Question 3

What is CISC?

Answer 3

a large instruction set

Question 4

Where are CISC instructions built into?

Answer 4

hardware

Question 5

What 2 places is CISC used?

Answer 5

embedded systems<br></br>microprocessors

Question 6

What is RISC?

Answer 6

a small instruction set

Question 7

What is each instruction in RISC the same as?

Answer 7

one line of machine code

Question 8

Where is RISC used?

Answer 8

everyday devices

Question 9

What is the benefit of RISC processors? 

Answer 9

pipelining is possible since each instruction takes one clock cycle

Question 10

Whare are the 2 benefits of using CISC processors?

Answer 10

1. compilers have to do less work<br></br>2. they require less RAM, since instructions are smaller

Question 11

What is a graphics processing unit (GPU)?

Answer 11

a co-processor made up of lots of independent parallel processors

Question 12

Whare are 2 uses of GPU’s?

Answer 12

1. image processing<br></br>2. machine learning

Question 13

What are multi-core systems?

Answer 13

systems where there are multiple cores that seperate fetch-execute cycles

Question 14

What are parallel systems? (2 things)

Answer 14

1. systems where multipe instructions can be completed at any given time<br></br>2. they dont require multiple cores and can use threading and pipelining instead
