What are the key facts about CISC?
Complex Instruction Set Computing • Has a larger instruction set • Requires more complex hardware/ requires cooling • Takes multiple clock cycles to execute an instruction • Tends to use more energy • Uses less RAM
What are the key facts about RISC?
Reduced Instruction Set Computing • Has a smaller instruction set • Requires less complex hardware/ requires little cooling • Takes one clock cycle to execute an instruction • Tends to use less energy • Uses more RAM
What are the key facts about a GPU?
GPU - Graphics Processing Unit • Is a co-processor specialised in rendering graphics • Specialist instructions available • 1000s of cores that can apply the same instruction to multiple pieces of data simultaneously (SIMD). • Suited to performing simple operations in parallel on larger data sets
What is a multicore system? What are the benefits? HINT: Very specific wording required
More than one processing unit in a single processor • Each core can independently process instructions at the same time. • Improves multi-tasking • Enables parallel processing • Increases the performance of the computer
What is parallel processing?
• Executing more than one instruction simultaneously • Can be achieved through multiple processors or distributed across multiple cores in a single CPU or GPU.
What are some limitations of parallel processing?
• Writing algorithms for parallel processing is more challenging. • Some tasks cannot be done in parallel due to relying on each other’s output
