Abstract

This paper gives a way of implementing a high-speed and reliable data conversion between UART and WLAN. After introducing the overview of our system, this paper shows the hardware structure and firmware design in brief. Then we analyze the bottleneck of the data conversion and give a way of how to improve and optimize the firmware to complete a highspeed and reliable data conversion in detail. We use DMA mechanism and data flow control to ensure the speed and reliability of data conversion. We add traffic self-adaptation feature to make the data conversion adapted to different data rate. We also show how to reduce the influence caused by the instability of wireless connection. Complete performance test will be taken at the end of this paper.
