    DMA buffer size

    hyun-chul.shin

      Dear forum members,

         

       

         

      I experimented bulk transfer speed with DMA buffer 32KB and 16 burst endpoint, and I got a speed 262MB/s.

         

       

         

      What is the relation between DMA buffer size and burst size?

         

       

         

      Is there any delay at buffer changing time? If not, I think CyUSB driver can't manipulate DMA machanism efficiently.

         

       

         

      Best Regards,

         

      HC
