HPS Trigger/DAQ requirements<br /> <br /> * SLAC TI implementation: in 3 month William will try to provide TI block, which will be extractable and used by both William and external groups; it can be slave only if easily to implement<br /> <br /> * multi-roc configuration: common TI for all of rocs, accessible by all rocs; in the same time only one roc is acknowledges TI; TI need acknowledge mask register, one bit per roc, and when all required bits set, TI acknowledged; TI fifo will be provided as separate copies for every roc; block level comes from TS to TIs and read by rocs; TI fifo contains minimum 3 32-bit words per trigger x 265 events per block; jlab TI will support 2 rocs, and we&#039;ll provide instruction how to make 8 and more roc versions; David and William will make a document describing new structure; for JLAB, busy from switch slot is there<br /> <br /> * configuration files: we have 2 formats - Ben&#039;s DiagGUIs and HallB/HallD config files, first used to adjust registers, and second used by readout lists; will continue to discuss the usage of those 2 formats<br /> <br /> 2. CLAS12 installation progress<br /> <br /> in progress; observes timing issues with TI (about 150ns trigger latency shift between sector 6 and sector 4 running ftof0/ftof1 with pcal trgger), will investigate; all the rest looks good</div>
