JPEG Decoder | ||
============ | ||
|
||
Jpeg Decoder example resides in ``L2/demos/jpegDec`` directory. The tutorial provides a step-by-step guide that covers commands for building and running kernel. | ||
|
||
Executable Usage | ||
---------------- | ||
|
||
* **Work Directory(Step 1)** | ||
|
||
The steps for library download and environment setup can be found in :ref:`l2_vitis_codec`. For getting the design, | ||
|
||
``` | ||
cd L2/demos/jpegDec | ||
``` | ||
|
||
* **Build kernel(Step 2)** | ||
|
||
Run the following make command to build your XCLBIN and host binary targeting a specific device. Please be noticed that this process will take a long time, maybe couple of hours. | ||
|
||
``` | ||
make run TARGET=hw DEVICE=xilinx_u250_xdma_201830_2 | ||
``` | ||
|
||
* **Run kernel(Step 3)** | ||
|
||
To get the benchmark results, please run the following command. | ||
|
||
``` | ||
./build_dir.hw.xilinx_u250_xdma_201830_2/host.exe -xclbin build_dir.hw.xilinx_u250_xdma_201830_2/jpegDecoder.xclbin -JPEGFile android.jpg | ||
``` | ||
|
||
JPEG Decoder Input Arguments: | ||
|
||
``` | ||
Usage: host.exe -[-xclbin -dataSetDir -refDir] | ||
-xclbin: the kernel name | ||
-JPEGFile: the path point to input *.jpg | ||
``` | ||
|
||
Note: Default arguments are set in Makefile, you can use other :ref:`pictures` listed in the table. | ||
|
||
* **Example output(Step 4)** | ||
|
||
``` | ||

Profiling | ||
--------- | ||
|
||
The hardware resource utilizations are listed in the following table. | ||
Different tool versions may result slightly different resource. | ||
|
||
##### Table 1 IP resources for jpegDecoder with huffman decoder(L1 IP) | ||
|
||
| IP | BRAM | URAM | DSP | FF | LUT | Frequency(MHz) | | ||
|-----------------------|----------|----------|----------|----------|---------|-----------------| | ||
| huffman_decoder | 5 | 0 | 12 | 6963 | 7344 | 286 | | ||
|
||
##### Table 2 IP resources for jpegDecoder with jfif parser and huffman decoder(L1 IP) | ||
|
||
| IP | BRAM | URAM | DSP | FF | LUT | Frequency(MHz) | | ||
|-----------------------|----------|----------|----------|----------|---------|-----------------| | ||
| kernel_parser_decoder | 5 | 0 | 12 | 7615 | 8382 | 257 | | ||
|
||
##### Table 3 Hardware resources for jpegDecoder with jfif parser, huffman, iq and idct (L2 kernel) | ||
|
||
| Kernel | BRAM | URAM | DSP | FF | LUT | Frequency(MHz) | | ||
|-----------------------|----------|----------|----------|----------|---------|-----------------| | ||
| jpegDecoder | 7 | 0 | 39 | 12298 | 13417 | 257 | | ||
|
||
Result | ||
------ | ||
|
||
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. | ||

|
||
##### Note | ||
``` | ||
| 1. MAX_DEC_PIX is for benchmark. If testcase image is larger than 20M, the value of MAX_DEC_PIX should be enlarged following the size of image. | ||
| 2. MAXCMP_BC is for benchmark. If testcase image is larger than 20M, the value of MAXCMP_BC should be enlarged following the size of image. | ||
``` | ||
# Level 1: HLS Modules | ||
|
||
The Level 1 APIs of Vitis Codec Library is presented as HLS C++ modules. | ||
|
||
This level of API is mainly provided for hardware-savvy developers. | ||
The API description and design details of these modules can be found | ||
in _L1 Module User Guide_ section of the library document. | ||
