The various signal processing functions are described below. Note that the coefficients used for each

arithmetic operation are set through the parallel I/F block. See the individual descriptions of each parallel I/F

block item for a detailed description of the parallel I/F block.

(a) Data path switch block

This block can switch the path of the data input to ports 1 and 2. The setting is as follows.

Select signal: 1 = Path switched, 0 = Path not switched (Set independently for R, G and B)
