FXCore
Audio Effects DSP
FXCore
FXCore from Experimental Noize is a DSP designed for creating audio effects in pro-audio devices. FXCore can operate as a standalone device when paired with appropriate CODECs where it generates all necessary clocks or as part of a more complex system where it will lock to the word clock and bit clock provided by another part of the system.
FXCore can store up to 16 programs and their associated register preset values in its internal FLASH memory so no external program storage is required. By storing preset values in the program header the designer does not need to use instructions just to set initial values.
With 6 potentiometer inputs and 5 switch inputs programs may have real time variable parameters and options such as chorus depth or number of stages in a phasor.
Integrated digital LFOs, ramps and noise generator allows designers to easily program phasors, flangers, chorus and other effects.
