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.
