- 1What are the two Categories of Processor?> CISC - Complex Instruction Set Computer
> RISC - Reduced Instruction Set Computer - 2What is a CISC Processor?> Complex Instruction Set Computer
> Uses a large instruction set to allow assembly language to use fewer instructions, as the built-in instructions deal with the additional steps
> Processor hardware and circuitry is complicated
> Compiler has to do little work when translating high-level language in assembly
> Complex instruction may take more than one cycle, so pipelining is impossible
> Used in PCs - x86 processors - 3What is a RISC Processor?> Reduced Instruction Set Computer
> Uses a small instruction set with only essentials bult-in
> Each instruction can be completed in a single clock cycle
> Assembly uses more code to achieve complex results
> Compiler has to do more conversion work
> More RAM is required to store programs
> Processing uses less energy; each instruction only takes a single clock cycle
> Pipelining can be used
> Requires fewer transistors and less complex hardware, leaving more room for general purpose registers and cache
> Used in smartphones, and ARM machines - 4What is a GPU?> Graphics processing unit
> Contains specialised circuits for handling graphics and image processing
> Uses many smaller cores that can process data in parallel efficiently
> Relieves the processing load on the CPU, freeing it to do other things
> Using high-end cards can vastly speed up software that renders graphics, i.e., 3D Design software (CAD) and games
> Can be used for large amounts of simultaneous data processing, such as AI training, or crypto if you're an asshole - 5What is a Parallel Processor?> Contains multiple cores
> Usually complete the same instructions on slightly different sets of data
> Includes CPUs and GPUs
