HSP_QSIGN
R/W
0
Quantization sign bit
24:16
HSP_QMULTIPLY[8:0]
R/W
0
Quantization multiply control
used to compensate for different weight sum in transposed
polyphase or color space matrix mode, remaining bits are fraction
(largest number is 511/512)
Value range:
. Instead of using values in the range of
the quantization shift HSP_QSHIFT should be modied to
gain more precision in the truncated result.
