Hi All, We just had prototype communication board using C6415. When I implemented the driver on WinNT 4.0 for this board and test it from host, I found: 1. the performance is not that good as I expect: 5Mbytes/s PCI read, 50Mbytes/s PCI write. 2. PCI burst write is not working very well. Sometimes the data is not written to dsp memory, I still got the old data when I read back. Also It looks like the PCI interface of C6415 is sensitive to other PCI activity on the PC because it is more likely to have error when I had a NIC plugged. Does anybody here use this DSP and do you have the same problem? A bunchs of thanks! William
