Systems Architecture

• Cache - small amount of high speed RAM built directly within the processor
• Register - small amounts of high speed memory contained with the CPU
• Advantages of using an embedded system : requires less power , cheaper to design and build , not much processing power needed, takes less space
• Clock speed in measured in Hz
• Factors affecting the CPU‘s performance : Clock speed , cache size , number of cores.
• Embedded system - a small computer that forms part of a larger system , device , or a machine
• Core - processing unit within the CPU
