A. Introduction of embedded development platform
The system used Liod embedded platform which takes
the IntelXScale PXA270 as processor developed by the

frequency is as high as 520 MHz, supporting the Intel
Wireless MMX and Step Speed technology. It also has high
performance, low power consumption, multi-function trait.
