EQ processing

Two channels of input data (re-sampled if necessary) at 96 kHz are provided to the EQ

processing block. In these blocks, 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

implemented by means of configuration parameter settings.

The entire EQ block can be bypassed for all channels simultaneously by setting the DSPB

bit to '1'. The CxEQBP bits can also be used to bypass the EQ functionality on a per channel

basis. Figure 3 shows the internal signal flow through the EQ block.
