Questions of ACU module

    We want to sum pixels values of an image, can we use PVP's ACU module?

    We set PVP_ACU_CTL.SFTINP to 3 and PVP_ACU_CTL.ACCFRAME to 1, and we should get a 32 bit summation of the input image, but now we get a zero value every time, should we set other registers or anything we have missing? thanks!
