Name | LUT | BRAM | URAM | DSP |
Platform | 196996 | 359 | 0 | 10 |
join_kernel | 128170 | 239 | 192 | 99 |
User Budget | 1105724 | 1657 | 960 | 9014 |
Percentage | 11.59% | 14.42% | 20.00% | 1.10% |
- 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 65.255ms to process 69.55MB data, so it achieves 1.04GB/s throughput.
