 Hi

 

When i test streamer example, data rate is about 38Mby. 

This was 8bit data set in fw. 

So i need more speed up and bandwidth . So what is exist way slave fifo's data rate up?

You have a total of 4K memory for Endpoints.

You can configure the endpoint to quad buffer to get the maximum buffer, if it is not already configured to quad buffer.

Thanks,

 Hi sai krisna

Yes i know fx2 slave fifo example is configurated quad buffer. 

Actually slave fifo have not enough speed for streamer. 

So i need to find a way how to make speed up in slave fifo mode. 

So, could you please let me know some ways?

Also if i setting WORDWIDE=1, is there any effort to speed side?

Are you getting 38MBytes per second or 38Mbps?.

If you are getting 38MBps then I don't think we can optimize further.

Yes. you can do that. If your sensor supports 16-bit data then you can do that.

Thanks,

sai krishna.
