Types of proccessors

Question 1

RISC

Answer 1

Reduced instruction set computing

Question 2

CISC

Answer 2

Complex instruction set computing

Question 3

Features of RISC

Answer 3

Has simpler hardware
more complicated software code
takes one cycle per instruction
can use RAM to handle intermediate results

Question 4

Features of CISC

Answer 4

Has more complex hardware
More compact software
takes more cycles per instruction
Can use less RAM as non need to store intermediate results

Question 5

Contemporary architecture

Answer 5

Modern high performance CPUs incorporated aspects of both (vn and h)
one main memory for both data and instructions
but CPU cache divided

Question 6

Von Nuemann architecture

Answer 6

Used in conventional processors in PCs,servers and embedded systems with only control functions
Data and programs share same memory
One bus is used to transfer both data and instructions
Programs can be optimized to size
single control unit

Question 7

Harvard architecture

Answer 7

Used in digital signal processing and in embedded systems,mobile communication systems,audio,speech and image processing systems
Instructions and data are held in separate memories
Parallel data and instructions buses may be used
Programs tend to be large

Question 8

One advantage of RISC

Answer 8

RAM is now cheap and the RISC ,use of RAM and software allows better performance processors at less cost

Question 9

One advantage of CISC

Answer 9

quicker to code programs

very little ram is(to store instructions) required since the code is relatively short

Question 10

Multi-core and Parallel systems

Answer 10

Multi core systems are able to distribute workload
across multiple processors cores,thus achieving significantly higher perfromance by performing several tasks in parallel
Quad core,Dual core

Question 11

Co-processors

Answer 11

A co-processor is an extra processor use to supplement the functions of the primary process(CPU
It generally carries out only a limited range of functions

Question 12

What is a GPU?

Answer 12

A GPU is a specialized electronic circuit which is very efficient at manipulating computer graphics and image processing.
GPUs have the ability to process these pieces of data in parallel: what is referred to as single instruction multiple data(SMID)
While designed for graphics GPUs are increasingly being used in many other fields such as:
modelling physical systems
audio processing
breaking passwords
machine learning
