8. ATCA-SRS Upgrade Path EicSys Gmbh is already working on an upgrade design driven by RD51 members applications (deadline Sept.-Oct. 14) Discussions with Eicsys on going regarding NSW application Two possible upgrade scenarios for NSW Trigger Processor application: – A) Replace V6 on blade with V7 – B) Put V7 on mezzanine and upgrade V6 on blade to K7 or a smaller V7 8

10. ATCA-SRS Upgrade Schedule and cost Current cost/blade: ~3k EUR (based on one full crate order, i.e. 14 blades) Upgrade cost driven mainly by the FPGA cost Variant B – Schedule ~ 12 weeks delivery for prototypes (Eicsys) – V7 mezzanine proto design by IFIN-HH (see backup) – Discussion: perhaps we may find a way to integrate the LAr AMC design Variant A may take longer 10
