Hi,
I've got a very strange problem when i tried to integrate one of our signal processing apps with TI NDK:
forewords....
Our app is processing a 42Msamples/sec datastream coming from EMIFa with emifa bw of about 25%.
The deadline for transfers is very short.
We are using DSK6455 1GHz with a custom made FPGA daughtercard for data I/O
The CPU utilization is about 2.2%.
symptoms:
We've configured the NDK to use DHCP.
If I start the application, when actual packets are transmitted/received over the network
my EDMA transfers are badly slowed and it misses some data.
Is there a way to configure bus access priority between EDMA and EMAC DMA?
Am I pointing the finger in the wrong direction?? (maybe the ndk disables ints for
sometime or some other conflict?)
Best Regards
Max
