UNIT-1 EMBEDDED COMPUTING
TWO MARKS
1. Define Embedded System. What are the components of embedded system?
An Embedded system is one that has computer hardware with software embedded in it as one of its most important component.
The three main components of an embedded system are
- Hardware
- Main application software
- RTOS
3. Define system on chip (SOC) with an example
Embedded systems are being designed on a single silicon chip called system on chip. SOC is a new design innovation for embedded system Ex. Mobile phone.
4. Give any two uses of VLSI designed circuits
A VLSI chip can embed IPs for the specific application besides the ASIP or a GPP core. A system on a VLSI chip that has all of needed analog as well as digital circuits. Eg. Mobile phone.
5. List the important considerations when selecting a processor.
- Instruction set
- Maximum bits in an operand
- Clock frequency
- Processor ability
6. What are the types of embedded system?
- Small scale embedded systems
- Medium scale embedded systems
- Sophisticated embedded systems
7. Classify the processors in embedded system?
1. General purpose processor
- Microprocessor
- Microcontroller
- Embedded processor
- Digital signal processor
- Media processor
2. Application specific system processor
3. Multiprocessor system using GPP and ASSP GPP core or ASIP core integrated into either an ASIC or a VLSI circuit or an FPGA core integrated with processor unit in a VLSI chip.
8. What are the important embedded processor chips?
