What's the best description for “embedded hard

2019-05-06 22:22发布

When I hear that, I always think about an mobile device. But why is the hardware "embedded" there? Isn't the whole device the hardware? Why is a personal computer no embedded hardware system?

In today's world embedded simply refers to a system with one or more of the following traits:

  • Single purpose (ie, not a general purpose computer, like your desktop)
  • Firmware rather than software - still software, but not as easily updated (flash, etc)
  • Hardware and software are designed together as a unit
  • Different, perhaps more rigorous testing as software updates are not desired
  • Real time computing
  • Memory integrated on the CPU
  • Microcontroller rather than microprocessor
  • Expected high reliability (you shouldn't have to reboot your dishwasher or microwave)
