Types Of Processor Flashcards
What is CISC
The large instruction set for accomplishing task in as few lines of assembly language as possible.
(Complex Instruction Set Computer)
What is RISC
Simple instructions, each taking one clock cycle, used to accomplish all the required operations in multiple general purpose register
(Reduced Instruction Set Computers)
Advantage of CISC
Quicker
Has a lot more instructions
Better performance
Simple to built
More efficient (compiler has very little work to do to translate a high level language statements into machine code, very little RAM is required to store instruction)
Disadvantage of CISC
To expensive
Can overheat
To heavy (To many specialised instructions had to be build into the hardware even though only 20% of them would be used In the average program)
Advantage of RISC
Lighter
Cheaper
Less chance to overheat
Quicker to code
Little space in RAM
Disadvantage of RISC
Slower
Less instructions
Not efficient
Ability of multi-core processor
Able to distribute workload across multiple processor cores, so higher performance.
What is a parallel system? ( not sure)
The multi core achieving significantly higher performance by performing several tasks in parallel.
E.g Google Chrome and Mozilla Firefox can run several concurrent processes.
What is the co-processor systems
An extra
