Large Buffer Support

In WARPLab 7.4 and earlier, all transmit and receive samples were stored in buffers of BRAM directly on the FPGA. As of WARPLab 7.5, these samples are buffered in the DRAM SODIMM attached to the WARP v3 hardware.

WARPLab 7.4 WARPLab 7.5 (4RF) WARPLab 7.5 (2RF)
Tx Maximum # of Samples 32768
Tx Maximum Duration at 40MHz Bandwidth 819.2 µs
Rx Maximum # of Samples 32768
Rx Maximum Duration at 40MHz Bandwidth 819.2µs

The table above summarizes the maximum buffer sizes for the WARPLab 7.5 design.
