DSP DESIGN
We are able to develop custom Digital Signal Processing systems based on standard DSP processors or custom digital circuits. We are familiar mainly with fixed point systems and with Motorola and Analog Devices DSP processors.
Experience in DSP design :
- telecommunication - PCM, DTMF, signals generators
- filtering - FIR, IIR, interpolation, decimation
- analysis of signals - FFT, cross-coleration
- audio application - equalizators, frequency wobbling
Design and realization flow
Function of the system is verified in standard DSP processor in the majority of projects. In many cases verificated IP cores are used.

Design process, evaluation and following production of DSP circuits
step by step in ASICentrum :
1. DESIGN SPECIFICATION
- customer's development assignment
- creation of the circuit specification
2. SYSTEM DESIGN
- DSP algorithm choice
- coeficients calculation, width of buses definition, etc.
- verification (MatLab)
3. REALIZATION WITH DSP PROCESSOR
- choice of the suitable processor
- program design and debuging (Design Kit processor)
- samples evaluation (measuring and testing)
- programming of the memories
4. REALIZATION WITH DIGITAL CIRCUIT
