With an MCRUSH and a ShaSLINK module, which make up the MROD-0 system,
the design has been studied. The hardware of the MCRUSH (documentation
: .pdf file) and the CRUSH module (used
for a study of the ROB design) are the same, only the FPGA is reprogrammed
with totally different logic. The MCRUSH can handle the data produced by
18 TDCs, do event building using the Tetris register (this signals availability
of the data of the event to be build), signal various error conditions
and potentially recover from errors. For testing the design the CSM has
been emulated with a ShaSLINK module (documentation)
and appropriate software sending data from the PCI-bus to the S-Link output. The functionality of the
FPGAs handling the input data streams in the MROD-1 is enhanced with respect to the functionality
available in the MCRUSH.
