PSoC further enriched with digital filter co-processor
The hardware digital filter co-processor integrated in the PSoC 3 and PSoC 5 devices combined with the easy-to-use PSoC Creator software enable advanced FIR or IIR digital filter implementations, AC noise rejection and many other filtering applications. PSoC 3 and PSoC 5’s hardware filter implementation can clean up and isolate even very weak signals, enabling small sensors to operate efficiently, and extracting modulated data in voice and communications systems. The new filtering solution is available as a drop-in “component” from Cypress’s PSoC Creator 2.0 design software. It was recently released in a “Component Pack” update that includes new peripheral functions. Cypress plans to deliver new Component Packs every eight weeks, adding new capabilities to its library of programmable components. The digital filter component is fully tested and characterized, it offers two independent filter channels, each of which can have up to four separately designed FIR or IIR stages in series. Customers can choose built-in standard window filter types or enter custom filter coefficients for maximum flexibility. Final hardware-optimized coefficient values as well as the graphical views of the expected results can be extracted for further analysis.
