|Why is this of interest ?
~ 2000 cards = ~ 100 crates = ~ 25 racks,
while with 16 ROBs per card this would be
~ 120 cards = ~ 6 crates = 2 racks
The first step to building a module having multiple ROBs, is the Compact Robin Using the SHarc (CRUSH).
In the CRUSH design study the aspects of compactness of design and low
power dissipation are addressed, while at the same time it has been attempted
to provide good programmability with respect to the required buffer management
and also to provide a good testability of the design.
The CRUSH hardware consists of an S-LINK input, an ALTERA for buffer management and data checking, a 256K*32 memory and a SHARC processor from Analog Devices.
|21 August 1997||Work is starting|
|9 September 1998||Design ready. PCB of the CRUSH is expected in two weeks time, simulations with actual SHARC processors have shown that the CRUSH can handle event rates up to 388 KHz.|
|4 November 1998||CRUSH is working. Power consumption is only 3 Watt.|
