Hardware
An embedded system consist of several components.
- Special Hardware: cryptographic.hardware.accelerators
- Hardware developers often use interfaces that can directly write to chip registers or flash: JTAG, debug ports/pins
- Wireless
Embedded systems are designed and often have drawbacks for their advantages. Low power consumption and low performance (benchmark: performance/watt comparisons) In contrast to the early age of computers many vendors do not publish data sheets or programming handbooks for their SoC, wireless chips, boards, etc...
