1.1 System Architecture
Processor
- Processes Data, Carries out instructions and Clock speed measured in Hertz
MHz
- 1 million instructions executed per second
GHz
- 1 billion instructions executed per second
Hertz
- Number of cycles per second
Embedded System
- A computer within another device (Firmware)
Cache
- Very fast
- Small amount of memory
- Increasing the size
- Reduces number of memory to disk transfer
- Speeds up processing of instructions
Core
- Where instructions are executed.
- Increasing the number of cores will increase the number of instructions per second
Clock speed
- The number of instructions per second.
- Doubling this will increase the number of instructions per second.
Execute
- Carries out the instructions
Instructions
- Information on how to operate, perform or maintain computer software/hardware
