CuEval2 Report

Bin Wei 8/13/2004 Introduction zBelle DAQ system Introduction (cont)

zCurrent Readout subsystem uses FASTBUS as system bus. zWeakness of FASTBUS ySlow trigger rate: 100-250Hz yBandwidth: around 10MB/s yCPU have to control whole transfer procedure. Introduction(cont)

zCOPPER readout subsystem yfast trigger rate: 10k-40kHz yBandwidth: 125MB/s (33MHz, 32bit PCI bus) yUsing DMA mode directly transfer data to memory without CPU control yThere are lots of PCI modules we can choose (Radisys 6315 as embeded CPU platform) COPPER II
