JEP HW status and FW integration plans Uli Schaefer and Pawel Plucinski Johannes-Gutenberg Universitaet Mainz Stockholm University

General remarks (Jet-FPGA) Jet-FPGA firmware upgrade to add RoIs to the real time output. Algorithm will report up to four RoIs. No side effects. The latency will not be affected. 16 registers (thresholds) in use (in total 117 including spare). Updated components: -Algorithm (including backplane data). -VME interface. -Glink stream (RoI-to-L2). -SPY Memory (output). -Clock manager (DCM: 160MHz and 80MHz). Diagnostic module (tests pattern, Jet and Sum-FPGA) implemented.

JEM: Jet-Energy and sum-FPGA Jet/FPGA sum/FPGA

Architecture of the jet-FPGA Architecture is modular, its easier to add, replace or modify... Component 1 Component 2 Component 3 Component 4 Component 5

Jet-FPGA – Backplane (JEM to CMX energy data) Eight 'presence' bits, indicating in which subregions jet RoIs were indentified. Four 2-bit 'fine-position' fields, one for each identified RoI Four 10-bit transverse energy sums for jet size 1 Four 9-bit transverse energy sums for jet size 2

GLINK Format – JEM ROI (L2)

Jet-FPGA register map (16 thresholds) Threshold and sizes Register contents: 2b cluster size 10b Et threshold VME interface and register space is updated, in total 117 registers. Location: offset Threshold default value is set to 0x3FF

Jet processing – New idea Thresholds and sizes register mapping (FCAL and CENTRAL): 8 sets of threshold/size registers, each specifying two jet sizes (JET Energies for larger and smaller window size) to be used and the minimum threshold for each. RoIO:Threshold1/Size1 Threshold2/Size2 RoI1:Threshold1/Size1 Threshold2/Size2 RoI2:Threshold1/Size1 Threshold2/Size2 RoI3:Threshold1/Size1 Threshold2/Size2 RoI4:Threshold1/Size1 Threshold2/Size2 RoI5:Threshold1/Size1 Threshold2/Size2 RoI6:Threshold1/Size1 Threshold2/Size2 RoI7:Threshold1/Size1 Threshold2/Size2

Diagnostic module (Jet and Sum-FPGA) JEM FW generating tests patterns at 160Mbps. JEM FW features: - Support for CMX timing procedure. - Stress patterns (ISI, Xtalk). - Built in as part of main firmware (persistent) - Pattern selectable from a ‘pre-defined’ menu: - No need to reserve-engineer inputs/menu to generate desired output. - Pattern consists of one special event and 255 repeating events. - Common components for Jet and Sum-FPGA. JET-FPGA ready, Sum-FPGA soon!

DCM structure (modified) Two extra clocks needed: 160MHz and 80MHz:

Conclusions / Plans Jet-FPGA FW is ready (tests ongoing), software version 1.0 is also ready. Algorithm supports 16 thresholds but other solutions is easy to implement. Diagnostic module (tests pattern) is ready, Jet-FPGA ready Sum-FPGA soon. JEM + BLT backplane tests (160Mbps) conducted at CERN. Integration (+ extra tests) with CMX scheduled on April. Some further work on Sum FPGA firmware required Uli / MZ 160Mb/s infrastructure exists due to implementation of “diagnostic module” Add “algorithmic” part Routing energy sums out to the output multiplexers Reorganize DAQ output stream Do further tests !
