,1 OCRSystems are designing a new CPU for a computer system that will be used for
video rendering. Part of the video rendering process is when the video is
exported. This is when the computer combines all of the separate video elements
together to form the final video.
(a) Describe two factors that affect the performance of the CPU.

(b) An important design consideration is whether OCRSystems use a CISC processor
type or a RISC processor type.
Describe one difference between a CISC processor and a RISC processor.
