Applications We have many applications which need camera Injection Laser Stabilization Beam Profile Monitors: OTR/YAG Experiments Requirement Resolution, Frame rate CCD sensitivity/Dynamic rage Thermal noise Beam synced acquisition capability Interface to control system LCLS standard IOC platform is EPICS/RTEMS/MV 6100 3/12/2008 Image Acquisition in LCLS 2 Sheng Peng pengsh 2003@yahoo. com

Possible Data Throughput on MVME 6100 The data throughput may be very high 640*480*2 bytes/pixel*120 Hz ~= 72 MB/s 1392*1040*2 bytes/pixel*15 Hz ~= 42 MB/s Theoretical maximum throughput Giga-Ethernet: ~100 MB/s USB 2. 0: 60 MB/s Firewire 1394 b: 100 MB/s 32 -Bit 66 MHz PCI: 264 MB/s 64 -Bit 66 MHz PCI: 528 MB/s 3/12/2008 Image Acquisition in LCLS 3 Sheng Peng pengsh 2003@yahoo. com

Possible Camera Interfaces There a few most popular interfaces in camera industry: Cameralink Ethernet LVDS(RS-644) USB 2. 0 Firewire (2. 38 Gbps for Base) (1 Gbps) (1. 923 Gbps) (480 Mbps) (400 Mbps/800 Mbps) Some decisions are easy: Ethernet is attractive Firewire is better than USB More camera choices Higher power Less CPU involvement RTEMS no USB stack Camera. Link is better than LVDS Camera. Link is serialized LVDS, so less wires More popular 3/12/2008 Image Acquisition in LCLS 4 Sheng Peng pengsh 2003@yahoo. com

Possible Camera Interfaces The most of cameras we are using now are all Camera. Link cameras so far We have two methods to integrate Cameralink interface into our control system: Ethernet PMC Frame Grabber 3/12/2008 Image Acquisition in LCLS 5 Sheng Peng pengsh 2003@yahoo. com

Ethernet Interface for Camera As always, I love Ethernet. But at that time, the choice we had was Camera. Link to Ethernet converter. Proprietary protocol, can’t get any info out from Pleora. Later on it turned to Gig. EVision. Vendor driver works with particular Ethernet chip Pleora and JAI PULNi. X and another ten companies started Gig. EVision We still need protocol/source code if we are not using Windows/Linux to interface to camera Even now, Camera. Link is probably more sophisticated. 3/12/2008 Image Acquisition in LCLS 6 Sheng Peng pengsh 2003@yahoo. com
