Profiling - Profiling - 2022.2 English

The hash semi-join design is validated on Alveo U280 board at 274 MHz frequency. The hardware resource utilizations are listed in the following table.

Table 37 Table 1 Hardware resources for hash semi-join

Name	LUT	BRAM	URAM	DSP
Platform	123976	202	0	4
join_kernel	67562	120	64	3
User Budget	1178744	1814	960	9020
Percentage	5.73%	6.62%	6.67%	0.03%

The performance is shown below.

In above test, table Lineitem has 3 columns and 6001215 rows and Orders does 2 column and 1500000 rows. This means that the design takes 18.914ms to process 80.12MB data, so it achieves 4.14GB/s throughput.
