Benchmark¶

Pictures¶

The data is used by benchmarks, our commonly used pictures are listed in table 1.

Table 1 Pictures for benchmark¶
Pictures	Format	Size
android.jpg	420	960*1280
offset.jpg	422	5184*3456
hq.jpg	444	5760*3840
iphone.jpg	420	3264*2448
lena_c_512.png	444	512*512

Performance¶

For representing the resource utilization in each benchmark, we separate the overall utilization into 2 parts, where P stands for the resource usage in platform, that is those instantiated in static region of the FPGA card, as well as K represents those used in kernels (dynamic region). The input is png, jpg, pik, e.g. format, and the target device is set to Alveo U200.

Table 2 Performance for processing pictures on FPGA¶
Architecture	Picture	Latency(ms)	Timing	LUT(P/K)	BRAM(P/K)	URAM(P/K)	DSP(P/K)
JPEG Huffman Decoder	android.jpg	0.889	270MHz	108.1K/7.9K	178/5	0/0	4/12
JPEG Decoder	android.jpg	1.515	243MHz	108.1K/23.1K	178/28	0/0	4/39
PIK	lena_c_512.png	16.0	300MHz	150.9K/439.4K	338/62	0/16	7/0

These are details for benchmark result and usage steps.

Test Overview¶

Here are benchmarks of the Vitis Codec Library using the Vitis environment and comparing with cpu().

Vitis Codec Library¶

Download code

These graph benchmarks can be downloaded from vitis libraries master branch.

git clone https://github.com/Xilinx/Vitis_Libraries.git
cd Vitis_Libraries
git checkout master
cd codec

Setup environment

Specifying the corresponding Vitis, XRT, and path to the platform repository by running following commands.

source <intstall_path>/installs/lin64/Vitis/2021.1/settings64.sh
source /opt/xilinx/xrt/setup.sh
export PLATFORM_REPO_PATHS=/opt/xilinx/platforms
