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 | 32,768 | 58,720,256 | 117,440,512 |
| Tx Maximum Duration at 40MHz Bandwidth | 819.2 µs | 1.468 s | 2.9360 s |
| Rx Maximum # of Samples | 32,768 | 134,217,728 | |
| Rx Maximum Duration at 40MHz Bandwidth | 819.2 µs | 1.6777 s | 3.3554 s |
The table above summarizes the maximum buffer sizes for the WARPLab 7.5 design. Since the buffer space is divided among RF interfaces, the 2RF design can store more samples than the 4RF design.
