What are the hardware elements in the embedded systems?
Hardware Elements in the Embedded Systems are as follows:
(i) Power Source
(ii) Clock Oscillator Circuit and Clocking Units
1. Suitable clock oscillator circuit
2. Real Time Clock (as System Clock)and Timers driving hardware and software
(iii) Reset Circuit
1. Reset onto Power-up
2. Internal and External Reset circuit
3. Reset onto Timeout of Watchdog timer
(iv) Memory
(v) Interrupts Handler
Interrupt Handling tool for the external port interrupts, input-output interrupts and RTC interrupts, timer and software interrupts and Exceptions
(vi) Linking Embedded System Hardware
• Interfacing and Linking circuit for the Buses through using the suitable multiplexers, and decoders, demultiplexers Interface the several system units
