[USRP-users] Re: RFNoC block and SEP buffer sizes

Rob, The "buff_size" parameter controls the "INGRESS_BUFF_SIZE" Verilog parameter used in the stream endpoint. It has a significant effect on streaming performance in the TX direction (host to USRP). A practical lower limit is two MTU-sized packets, and the rfnoc_image_builder will coerce it to at

[USRP-users] RFNoC block and SEP buffer sizes

I am having some trouble building a custom RFNoC 4 FPGA design and so I am looking to reduce the footprint. One easy thing to try is to reduce various buffer sizes such as the ingress buffer size on the streaming endpoint or the incoming RFNoC block fifo depths. But, I am wondering if there are pr

Hello Jonathon Your suggestion have worked but what I see is after transmitting certain amount of IQ samples it again generates a timeout error. My flowgraph now looks like this: Radio=>DDC=>fir filter=>fifo=host Regards Snehasish Sent from Mail
