Microphone arrays

We are long-time experienced in the field of process control (that is real time plus data acquisition with sensors).

The advanced digital techniques that come from musical research - which most of our staff are interested in - provide further stimula.

Therefore we gained a very good knowledge in real time and code optimization.

Parallelism and kernel software

We have developed a scalable kernel for a parallel system based on Ariel boards equipped with four Texas Instruments TMS320C40 DSP chips. The system is a MIMD machine featuring ring topology and "pipeline" load sharing.

We write optimized code

We are experienced C and C++ programmers, as well as assembler code developers. Nowadays optimized C compilers for general purpose CPUs have made assembler programming almost unnecessary; but in the case of strongly pipelined DSP, C language can introduce huge overloads. We are able - for TI C30 and C40 and for AD SHARC - to write optimized code up to ten times in performance - a desirable feature for real time applications and cost control.

Complex algorithms

We manage time-frequency transforms (DFT, FFT, Winograd, Spectrogram, Gabor-like, wavelet based multiresolution analysis and synthesis), non-linear filters (Chebitcheff, Laguerre), as well as time and frequency warping techniques.
