PCI interface on C6415

Started by zhang_zhh February 20, 2002
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!
