| Abstract: | At present,the embedded system based on S3C2440 chip is being used widely,but the number of USB ports of S3C2440 is relatively small,and difficult to meet the need.The design with the use of AU9254,can solve this problem and improve system performance.The embedded system which adopts this design and mount Linux operating system can work normally with U disk,mouse,keyboard,and it also provides external Interface for many modules.The design can not only improve overall system performances,but also reduce cost... |
