PCI (1993), for reliability with higher performance v Many serial interconnects on backplane ³ 2. 5 Gbps each (10 Gbps in the future) » One card covers all phones in a small city with a certain implementation v IPMI surveillance/remote-management for reliability u AMC (Advanced Mezzanine Card for ATCA) v Serial interconnects, IPMI, good part of ATCA ³ Like IP-module to VME, PMC to c. PCI u Micro. TCA (2008) v AMC card itself is powerful v Direct slot-in AMC cards in a Box ³ Commercial I/O cards for industry are available EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, Oct. 2010. 5

Micro. TCA LLRF Controller w/ EPICS Accelerator Controls u. VME + Unix (1990~) v Standard EPICS configuration ³ With many third layer field networks u. Every controller on network (1993~) v Single layer in physical, two layer in logical u. Every controller with EPICS IOC (2005~) v Channel Access everywhere ³ For longer term maintenance EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, Oct. 2010. 6

Micro. TCA LLRF Controller w/ EPICS u. Let’s employ Channel Access on m. TCA Backplane ! u. Let’s embed EPICS IOC on to Each m. TCA/AMC Card ! Miura and Furukawa EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, Oct. 2010. 9

Micro. TCA LLRF Controller w/ EPICS IOC on Micro. TCA u. Natural to put IOC on m. TCA LLRF Controller ³ And on ATCA LLRF Controller u. Chose Gb. Ethernet as a main media on the backplane interconnect v Somewhat unique v Some other institutes chose PCIe as the media u. Chose Power. PC core on Virtex 5 v ML 507 of Xilinx as a good reference u. Linux on Power. PC v No realtime processing is necessary ³ In the future, we may use realtime (<100 ms) feature of Linux EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, Oct. 2010. 10

Micro. TCA LLRF Controller w/ EPICS RF Group Micro. TCA based LLRF Controller v Single-width full-height module v Without physics experiment extension (we started earlier) ³ Front-panel connectors (rather busy) v Digital part and Analog part are separate ³ ³ ³ ADC 16 bit, 130 Msps, x 4 DAC 16 bit, 500 Msps, x 4 Virtex 5 with PPC 440 RAM 640 MB, Flash 64 MB Also monitor card with the same digital part w ADC 14 bit, 400 Msps, 1. 4 GHz, x 2 v Fabrication subcontracted ³ Mitsubishi Electric Tokki System ³ Windriver Linux (ML 507 is supported) EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, Oct. 2010. 11
