The hash multi-join design is validated on an AMD Alveo™ U280 board at a 200 MHz frequency. The hardware resource utilizations are listed in the following table.
Name | LUT | BRAM | URAM | DSP |
Platform | 130582 | 204 | 0 | 4 |
join_kernel | 133390 | 271 | 192 | 99 |
User Budget | 1172138 | 1812 | 960 | 9020 |
Percentage | 11.38% | 14.96% | 20.00% | 1.10% |
The performance is shown below. In above test, table Lineitem
has three columns and 6001215 rows, and Orders
has one column and 227597 rows. This means that the design takes 76.899 ms to process 69.55 MB data, so it achieves 0.88 Gb/s throughput.
