2023.2 English

Now the test bench will run the case 10 times to calculate an average speed of the kernel

# build and run JPEG Decoder using U200 platform
make run TARGET=hw PLATFORM=xilinx_u200_gen3x16_xdma_2_202110_1.xpfm

Building xclbin will take about 4 hours, take a coffee break.

Example output:

Found Platform
Platform Name: Xilinx
INFO: Found Device=xilinx_u200_gen3x16_xdma_2_202110_1
INFO: Importing kernelJpegDecoder.xclbin

INFO: Kernel has been created
INFO: Finish kernel setup

INFO: Finish kernel execution
INFO: Finish E2E execution
INFO: Data transfer from host to device: 108 us
INFO: Data transfer from device to host: 726 us
INFO: Average kernel execution per run: 1515 us

INFO: android.yuv will be generated from the jpeg decoder's output
INFO: android.yuv is generated correctly

So for this 1280x960 android.jpg file the output throughput is about 1216MB/s ( (1280x960x3)/2/1515 ).

To check the output yuv file, download https://sourceforge.net/projects/raw-yuvplayer/ . Then upload the rebuild_image.yuv, set the right sample radio and custom size on the software, and check the yuv file.
