1.1.2 Types of processor- Harvey

Small instruction set Less complex instructions Quicker to execute Each instruction is one line of machine code and takes one clock cycle Used in embedded systems

Large instruction set Complex instructions Complex hardware Requires multiple machine cycles per instruction Can’t make use of pipelining

A GPU (Graphics Processing Unit) is a specialized processor designed to accelerate rendering of images, videos, and animations by performing parallel processing tasks

More efficient use if RAM CISC requires less RAM since code is shorter Compiler has to do less work Used in laptops/ desktop computers Many specialised instructions made even though only a few of them are used.

Pipelining is possible Each instruction takes one clock cycle Simpler hardware Smaller number of instructions Simpler instructions Used in smartphones, tablets/ embedded systems In RISC processors compilers have to do more work to translate high level code into machine code

Have multiple independent cores that can complete instructions separately this improves performance.

Parallel systems use multiple cores/ processors Tasks run at exactly the same time This increases speed Eg. A quad-core cpu rendering different parts of an image at the same time

Usually multi-core systems perform better in larger projects than parallel systems

A co-processor is a secondary processor designed to supplement the activities of a primary processor
