Uso di tools per 'Rapid Prototyping' nello sviluppo di algoritmi DSP complessi.

Rapid prototyping is becoming a new approach in advanced Digital Signal Processing development. It allows fast tuning of complex algorithms without spending many work-days coding in typical DSP oriented languages, assembler or C/C++ dialects. With the advent of Mathworks MATLAB's Real Time Workshop (RTW) is now possible to compile, load and execute graphically designed Mathworks Simulink models into a real DSP platform. RTW supports many Developer Starter Kit DSP boards, including the pretty powerful Texas Instruments C6000 series. As described in this document, we developed an HW system based on the TMS320C6711 DSK (then replaced by a TMS320C6713 DSK), enclosing it in a chassis together with additional analog circuitry. This system has been used for testing a Virtual Dubbing algorithm, currently under development at Musical & Architectural Acoustic Lab. (FSSG-CNR, Venice, Italy) proving the advantages of rapid aided prototyping approach. Some evaluation on preliminary results is given.
