Hi3516开发指南

其实我刚刚接触3516.

下面给出一个例子，来说明3516如何调用api函数。

HI_S32 hi3516_frame_thresh(HI_U32 PhyAddrSrc,HI_U32 PhyAddrDst,FRAME_SIZE frame_size){
HI_S32 s32Ret = HI_SUCCESS;

    IVE_SRC_INFO_S stSrc;
    IVE_MEM_INFO_S stDst;
    IVE_HANDLE IveHandle;
    HI_BOOL bInstant = HI_TRUE;

HI_BOOL bFinish, bBlock;

IVE_THRESH_CTRL_S pstThreshCtrl;

    stSrc.enSrcFmt = IVE_SRC_FMT_SINGLE;
    stSrc.stSrcMem.u32PhyAddr = PhyAddrSrc;
    stSrc.stSrcMem.u32Stride = frame_size.Stride;
    stSrc.u32Height = frame_size.Height;
    stSrc.u32Width = frame_size.Width;

stDst.u32PhyAddr = PhyAddrDst;
stDst.u32Stride = frame_size.Stride;

    pstThreshCtrl.enOutFmt=IVE_THRESH_OUT_FMT_BINARY;
    pstThreshCtrl.u32Thresh=30;
    pstThreshCtrl.u32MinVal=0;
    pstThreshCtrl.u32MaxVal=255;

    getstarttime();
    s32Ret = HI_MPI_IVE_THRESH(&IveHandle, &stSrc,&stDst, &pstThreshCtrl,bInstant);
    //bBlock = HI_FALSE;
    bBlock = HI_TRUE;
    s32Ret = HI_MPI_IVE_Query(IveHandle, &bFinish, bBlock);
    if (HI_SUCCESS == s32Ret){
        if(bFinish==HI_TRUE)
            printf("Success: %s finished!\n", __FUNCTION__);
        else
            printf("Success: %s Unfinished!\n", __FUNCTION__);
    }
    else
        printf("Error: %s=%x\n",__FUNCTION__,s32Ret);
    getendtime(__FUNCTION__);

    return s32Ret;
}

void main（）

{

。。。

hi3516_frame_thresh(PhyAddrFilter,PhyAddrThresh,frame_size);

。。。

其中PhyAddrFilter和PyhAddrThresh指向缓存池内存块地址。
