In Section 2, the top-level decimation filter chain system is introduced. The number format system and basic arithmetic units are discussed in Section 3. Section 4 analyses the hardware architecture implementations for each decimation filter. The benchmark setup is shown in Section 5. In Section ...

11.2.1 Output Filter Stage The digital filter can output data following any stage in the filter chain. The output filter stage is se- lected by the FSEL bits in the FILTCFG register. Taking data from the SINC or FIR1 filter stages re- duces the overall decimation of the filter chain ...
This blog presents two very easy ways to test the performance of multistage cascaded integrator-comb (CIC) decimation filters [1]. Anyone implementing CIC filters should take note of the following proposed CIC filter test methods.Introduction ...

Describes the strategy that the Overlay Mixer Filter filter uses to scale the video image down to a smaller size.
The decimation operation can be moved through the DSP processing chain to the beginning, so that your FIR filter, and your NCO can operate at 8MHz. If you wanted to extract all 5 x 8MHz channels from within your 40MHz band, then you could use a "polyphase filter", which is essential...
