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
- Mainapplication software
- RTOS
- In what ways CISC and RISC processors differ?
2. 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. Giveany 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
- What are the types of embedded system?
Small scale embedded systems
Medium scale embedded systems
