EQ processing
Two channels of input data (re-sampled if necessary) at 96 kHz are provided to the EQ
processing block. In this block, up to four user-defined biquads can be applied to each of the
two channels.
Pre-scaling, DC-blocking, high-pass, de-emphasis, bass, and tone control filters can also be
applied based on various configuration parameter settings.
The entire EQ block can be bypassed for all channels simultaneously by setting the DSPB
bit to 1. And the CxEQBP bits can be used to bypass the EQ function on a per channel
basis. Figure 3 shows the internal signal flow through the EQ block.
