GritTec sells developed miniature DSP modules on the base of TI TMS320VC33 DSP, which were used for "M-NC" device of active noise cancellation, in real time systems.
Current DSP board is useful for developers to quickly debugging of DSP algorithms and audio processes with float-point operations.
DSP board consists of two parts: general board and mother board, see fig.
General board is used to perform DSP code of developer on the base of TI TMS320VC33 processor, loaded from the boot loader. General board has completely final functionality that allows to use it for integration into hardware solutions of third parties.
Mother board is used for debugging general board with JTAG emulator and connecting of audio input/output connectors with stereo 3.5 mm. jacks.
'm-board-vc33' Audio DSP board is completely compatible with all debugging tools for TI TMS320VC33 DSP processor.

Applications:

Mobile and stationary radio systems;
VOIP telephony;
Real time systems for audio processing of speech signals.
