Optimization of a real-time adaptive self-tuning filter implemented on a Texas Instruments TMS320C30 floating point DSP

A real-time adaptive self-tuning digital filter has been implemented for audio-band using the TMS320C30. An 81-tap finite impulse response (FIR) filter was utilized. Attempts to optimize the filter performance produced a signal-to-noise ratio improvement of 13 dB a misadjustment noise reduction by a factor of 50% from u=0.01 to u=0.001 while yielding adaptation speed degradation by a factor of 8.<
