The hash join v4 design is validated on Alveo U280 board at 240MHz frequency. The hardware resource utilizations are listed in the following table.
Name | LUT | BRAM | URAM | DSP |
Platform | 201457 | 359 | 0 | 10 |
join_kernel | 110093 | 187 | 256 | 19 |
User Budget | 1101263 | 1657 | 960 | 9014 |
Percentage | 10.00% | 11.29% | 26.67% | 0.21% |
- The performance is shown below.
- In above test, table
Lineitem
has 3 columns and 6001215 rows andOrders
does 1 column and 227597 rows. This means that the design takes 1354.795ms to process 69.55MB, so it achieves 51.33MB/s throughput.
