  1. data transfer rate is very low on PXA270/ISP1761 use a default WinCE/Linux driver.
    currently I pending the work. if anyone want optimazation.
    1. not enable SOF Interrupt
    2. check Client Driver and PTD data transfer method and bandwidth. (using DMA to transfer is better)
     

  2. thanks for your advice. I will try to optimazation.
