GBT oriented firmware for Data Processing Boards for CBM

Abstract

The Data Processing Boards are the important component of the development version of the CBM readout system. Even though in the final version they will be replaced with the new Common Readout Interface PCIe boards, they are still used for development and testing of new firmware features and for operation during the beam tests. The paper describes the current state of the DPB firmware development. The special emphasis is put on the functionalities related to support for various configurations of the GBTX-connected front-end electronics.
