I have many years of experience in implementing various FPGA based DSP algorithms, such as:
Up and Down frequency converters, interpolators and decimatiors,
FIR, IIR, CIC filters,
Adaptive filters,
Fast Fourier transform,
Forward Error Correction,
Correlation, signal energy calculation etc.,
Video data capture,
Graphical on-screen display,
Real time visual objects counter,
And so on.
My Real-Time / Embedded programming experience is based on several tens projects with Altera Nios II Embedded soft processor and Microchip PIC microcontrollers.
