Abstract :
The FDSP (Fuzzy Digital Signal Processor) is a new device that combines fuzzy processor and DSP in a single core well adapted to be hosted by low cost microcontrollers. The FDSP offers economic solution to implement adaptive fuzzy digital signal processing. The fuzzy processor acts as a controller or an adaptive element to a DSP system to implement adaptive filters, noise cancellers, estimators, channel equalizers, etc. We demonstrate the use of the FDSP to implement hard disk drive controller that combines quasi-optimum seek-track control, adaptive noise filters, and velocity estimator. Other applications of the FDSP include non-linear imaging filters and motion estimators and other systems for multimedia processing
