For a study of the ROB Complex the CRUSH and ShaSLINK modules are used. They are both based on the ADSP-21060 SHARC processor. These modules are also used for a study of the implementation of the MDT RODs (MROD). Based on the results of this study a prototype is designed, the MROD-1. In the MROD-1 ADSP-21160 SHARC processors are used. It consists of a 9U VME board with 6 S-link inputs, an S-link output and a VME64x interface. It is foreseen that the FPGAs on the board can be reconfigured such that a 6 input ROB Complex can be realized.

Picture of the CRUSH board. The board is fully functional at the nominal processor speed (40 MHz, the maximum 32-bit word frequency of the input S-link is equal to this number). Typical power dissipation (without S-link card) is 2 - 3 W.
Picture of the ShaSLINK board. The board is fully functional and is
able to transfer data accross the PCI bus at full speed. The maximum 32-bit
word frequency on the S-link output is 40 MHz. The board can be used as
a programmable S-link data source.
