Abstract

In this contribution a new concept for the rapid development of real-time prototypes for digital signal processing algorithms on a General Purpose Personal Computer (GP-PC) based on the Windows operating system (Windows OS) is presented. In this approach, hardware and algorithm related programming issues are separated in order to liberate the designer from problems which are not related to the development of the algorithm. The described platform therefore admits the complete focus of the developer on algorithmic aspects. We will present the system along with example applications from acoustic echo cancelation and multichannel noise control. A third example from the field of speech coding demonstrates the computational power available on a state-of-the-art PC.
