Processor Power Objectives Can you find the processing power for the following items: BEGINNER: Describe the purpose and state the function of a CPU. ADVANCED: Explain common characteristics of a CPU and how they effect performance. EXPERT: State the purpose of embedded systems and give examples. i. Phone 7 i. Pad Air Desktop/Laptop Question: How is the power measured? Can you compare all of the devices?

Processor Purpose What is the purpose of the processor? Objectives BEGINNER: Describe the purpose and state the function of a CPU. ADVANCED: Explain common characteristics of a CPU and how they effect performance. EXPERT: State the purpose of embedded systems and give examples. • • The processor is “the brains of a Computer System” It Processes Data Carries out instructions (Executes Them) Processors have a Clock speed measured in Hertz (Number of Cycles Per Second) Can you explain the following terms: Processor Speed Cores How do the above affect performance? Cache Size

Processor Power Objectives BEGINNER: Describe the purpose and state the function of a CPU. ADVANCED: Explain common characteristics of a CPU and how they effect performance. EXPERT: State the purpose of embedded systems and give examples. Processor Speed Measured in Hertz (Hz), Typical Speeds have spanned across MHz and GHz, 1 GHz Processor executes 1 Billion Instructions per second and 2 GHz Processor executes 2 Billion Instructions Per Second. Doubling the clock speed will double the number of instructions executed per second. Cores Each processor has a “core” in which instructions are executed. Processors can be multi-core (Dual Core, Quad Core, 8 Core). Each core executes instructions independently. Quadrupling the number of cores may quadruple the number of instructions executed per second. Cache Size Cache is very fast, and usually a very small amount of memory on the processor chip. It acts as an intermediary between the processor and the Main Memory. As programs are executing – the Cache holds commonly used instructions. Increasing the cache size will reduce the number of memory to disk transfers and thus may speed up processing of these instructions.

Embedded Systems Objectives BEGINNER: Describe the purpose and state the function of a CPU. ADVANCED: Explain common characteristics of a CPU and how they effect performance. EXPERT: State the purpose of embedded systems and give examples. What is an embedded system? A computer System that is made up of both Hardware and Software, often known as Firmware. It’s usually for very specialised tasks and doesn’t usually contain an operating system. An example is a dishwasher. 1. Produce a list of embedded systems found around the home. Would you ever need to write a proper program for these? Why do you think that we have embedded systems? What are the benefits and drawbacks of embedded systems?
