axiStrm2xfMat is used by consumer kernel to support streaming data transfer between two kernels. Consumer kernel receives data from producer kernel through kernel streaming interface which is defined by hls:stream with the ap_axiu< PTR_WIDTH, 0, 0, 0> data type. axiStrm2xfMat would read from AXI stream and write into xf::cv:Mat based on particular configuration (bit-depth, channels, pixel-parallelism) the xf::cv:Mat was created.

void axiStrm2xfMat(hls::stream<ap_axiu<PTR_WIDTH, 0, 0, 0> >& srcPtr, xf::cv::Mat<MAT_T, ROWS, COLS, NPC>& dstMat)
| Parameter | Description |
|---|---|
| PTR_WIDTH | Data width of the input pointer. The value must be power 2, starting from 8 to 512. |
| MAT_T | Input Mat type. Example XF_8UC1, XF_16UC1, XF_8UC3 and XF_8UC4 |
| ROWS | Maximum height of image |
| COLS | Maximum width of image |
| NPC | Number of pixels computed in parallel. Example XF_NPPC1, XF_NPPC8 |
| srcPtr | Input image of type hls::stream<ap_axiu<PTR_WIDTH, 0, 0, 0> > |
| dstMat | Output image of type xf::cv::Mat |
