types of processors

Question 1

RISC

Reduced Instruction Set Computers

Answer 1

• In these processors, there is a ​small instruction set​.
• Each instruction is approximately ​one line of machine code​
• takes one clock cycle.

Question 2

CISC

Complex Instruction Set Computers

Answer 2

• large instruction set​.
• aim is to try and accomplish tasks in as few lines of assembly code as possible.
• These instructions are built into the hardware​.

Question 3

RISC facts

compiler, RAM, pipeling

Answer 3

• The compiler has to do more work to translate high level code into machine code.
• More RAM is required to store the code.
• Pipelining is possible since each instruction takes one clock cycle.

Question 4

CISC facts

compiler,RAM, specialised instructions

Answer 4

• The compiler has less work to translate high level code into machine code.
• Less RAM is required since code is shorter.
• Many specialised instructions are made, even though only a few of them are used.

Question 5

multicore

Answer 5

• Multi-core CPUs have ​multiple independent cores​
• can complete instructions separately
• results in higher performance

Question 6

parallel systems

Answer 6

• When a computer has multiple cores it can use parallel processing where each core can work on the same task to complete it more quickly,
• or each core can work on separate tasks at the same time

Question 7

threadig

Answer 7

• Threading allows different parts of a computer program to execute simultaneously.
• This enables multiple operations to be performed simultaneously rather than sequentially
• improves the speed and efficiency of applications.

Question 8

Graphics Processing Unit (GPU)

Answer 8

A graphics processing unit (GPU) is a device which work in parallel making it very efficient at completing ​repetitive tasks such as image processing and machine learning

GPUs are a type of ​co-processor​ (a secondary processor designed to supplement the activities of the primary processor).
