Give one use an architect firm might have for GPUs
• to render models of proposed buildings • run CAD software • run modelling calculations
Compare 2 differences between a RISC architecture and a CISC architecture
• CISC has a larger instruction set • RISC has a smaller instruction set • CISC requires more complex hardware/ requires cooling • RISC requires less complex hardware/ requires little cooling • CISC takes multiple clock cycles to execute an instruction • RISC takes one clock cycle to execute an instruction • CISC tends to use more energy • RISC tends to use less energy • CISC has more addressing modes • RISC has fewer addressing modes • CISC uses less RAM • RISC uses more RAM
Describe a benefit of making the CPU a multicore CPU
• Multiple instructions can be processed at the same time • Improves multi-tasking • Enables parallel processing • Increases the performance of the computer
Describe how parallel processing would increase the performance of a computer system that will be used for video rendering
• Parallel processing will allow multiple separate jobs/instructions/FDE cycles to run concurrently. • Longer rendering jobs can be split, shortening the overall time taken. • Different CPUs/cores can tackle different frames/sections/components of the video simultaneously.
