Easy user configuration of filters running on the Digital Filter Block (DFB) available in some PSoC 3, PSoC 5 and PSoC5 LP devices.
Supports two separate filter channels, each one constructed as a cascade of up to four separately designed stages.
Multiple FIR and IIR (Biquad) filter methods (including user coefficient entry) give great flexibility
Final coefficient values can be extracted for further analysis
The customizer for the Filter component allows you to configure digital filters on one or two data streams passed to the Digital Filter Block (DFB), using DMA, interrupts, or polling to manage data flow. The DFB’s 128 data and coefficient locations are shared as needed between the two filter channels. The customizer reports (but does not set) the minimum bus clock frequency required to execute the filtering within the user-declared sample interval.
This component supports a huge number of use cases. If you encounter something unusual when using it, report it (with a good description of what you did to cause it) to email@example.com so Cypress can investigate.
