Description

Scaling and rotating coefficient error register

Fields

TX_DSCR_VB_ERR_ST

The error is that the scaled VB plus the offset of Y coordinate in 2DDMA receive descriptor is larger than VA in 2DDMA receive descriptor.
TX_DSCR_HB_ERR_ST

The error is that the scaled HB plus the offset of X coordinate in 2DDMA receive descriptor is larger than HA in 2DDMA receive descriptor.
Y_RX_SCAL_EQUAL_0_ERR_ST

The error is that the PPA_SR_SCAL_Y_INT and PPA_SR_CAL_Y_FRAG both are 0.
RX_DSCR_VB_ERR_ST

The error is that VB in 2DDMA receive descriptor plus the offset of Y coordinate in 2DDMA transmit descriptor is larger than VA in 2DDMA transmit descriptor
YDST_LEN_TOO_SAMLL_ERR_ST

The error is that the scaled image width is 0. For example. when source width is 14. scaled value is 1/16. and no rotate operation. then scaled width would be 0 as the result would be floored.
YDST_LEN_TOO_LARGE_ERR_ST

The error is that the scaled width is larger than (2^13 - 1).
X_RX_SCAL_EQUAL_0_ERR_ST

The error is that the scaled image height is 0.
RX_DSCR_HB_ERR_ST

The error is that the HB in 2DDMA transmit descriptor plus the offset of X coordinate in 2DDMA transmit descriptor is larger than HA in 2DDMA transmit descriptor.
XDST_LEN_TOO_SAMLL_ERR_ST

The error is that the scaled image height is 0. For example. when source height is 14. scaled value is 1/16. and no rotate operation. then scaled height would be 0 as the result would be floored.
XDST_LEN_TOO_LARGE_ERR_ST

The error is that the scaled image height is larger than (2^13 - 1).
X_YUV420_RX_SCALE_ERR_ST

The error is that the ha/hb/x param in dma2d descriptor is an odd num when enable yuv420 rx
Y_YUV420_RX_SCALE_ERR_ST

The error is that the va/vb/y param in dma2d descriptor is an odd num when enable yuv420 rx
X_YUV420_TX_SCALE_ERR_ST

The error is that the ha/hb/x param in dma2d descriptor is an odd num when enable yuv420 tx
Y_YUV420_TX_SCALE_ERR_ST

The error is that the va/vb/y param in dma2d descriptor is an odd num when enable yuv420 tx
