如题现在本人已经在ZYNQ上建立好了视频通路:通路的大概情况如下:
/************config hls ip********/
voidConfigureHlsIP(XImgprocess_top *ImgProcess)
{
ImgProcess->Control_bus_BaseAddress = XPAR_IMGPROCESS_TOP_0_S_AXI_CONTROL_BUS_BASEADDR;
ImgProcess->IsReady = XIL_COMPONENT_IS_READY;
XImgprocess_top_EnableAutoRestart(ImgProcess);
XImgprocess_top_SetRows(ImgProcess, 480);
XImgprocess_top_SetCols(ImgProcess,640);
XImgprocess_top_InterruptDisable(ImgProcess, 0xFFFFFFFF);
XImgprocess_top_InterruptGlobalDisable(ImgProcess);
XImgprocess_top_Start(ImgProcess);
}
int main()
{
init_platform();
usleep(100000);
print("Hello World\n\r");
ConfigureHlsIP(&ImgProcess);
// MM2S
Xil_Out32(XPAR_AXI_VDMA_0_BASEADDR + 0x00, 0x008B); // enable run, circular_park, GenlockEn, GenlockSrc

return0;
}
但是现在有一个问题,这个通路是采集摄像头数据,然后hls_IP处理,之后dma存储图像和读出图像显示,现在我想在SDK中添加自己的一些简单的对图像数据的操作我该怎么做?这个通路是自动的吧,从采集图像到显示图像,我要是在sdk中直接操作内存地址中的图像数据会发生数据冲突,该怎么办,求给个思路
