Peripheral Daughter Boards for Data Acquisition and Preprocessing

D.Module peripheral boards expand the functionality of D.Module DSP boards with data acquisition and preprocessing as well as adding supplemental interfaces.

Utilization in the D.Module DSP System

The standardised D.Module architecture, mechanics and pinout enables the realisation of a complete processing chain by stacking the require boards.

FPGA-based Data Preprocessing and Interface Expansion


The D.Module2 architecture supports the insertion of the FPGA daughter board between a data acquisition frontend and a DSP board for preprocessing. Likewise this Spartan-6 based board can be used to provide additional interfaces or even operate as a stand-alone system. Combined with the D2.Base-FMC base board, the D.Module2.6SLX45T forms a complete solution which can be used with high-speed data acquisition mezzanine cards conforming with the Vita 57 FMC standard.
