worki= ng with a vendor to implement some basic image processing capabilities in s= ome custom hardware so that it can happen at ~100Hz. Things like projection= s and gaussian fits which we will want as well.
Silicon So= ftware, our framegrabber vendor, has significant support for FPGA-based acc= eleration of
image processing. See

http://www.silicon-software.com/smartapplet= s.html
http://www.silicon-software.com/visualapplets.html

for= more details. The PCO engineers are supposedly making a custom mod to the = microEnable IV firmware in order to support enhanced on-board compression f= or our sCMOS camera, but I'd guess what they actually doing is using the Sm= artApplets software.
The SmartApplets run on-board the framegrabber in r= eal time, while the VisualApplets are used for post-processing data saved t= o files. We receive a license for the FPGA software as part of our framegra= bber purchase.

I don't know if Visual Applets already supports proje= ction and gaussian fits but it sounds like adding new features is not hard.= Silicon Software also sells standalone FPGA "Pixel Plant" cards (see botto= m of http://www.silicon-software.com/microenable4.html) that can run Visual= Applets alongside or without one of their framegrabber cards. Here are the = prices and specs:

PixelPlant PX100 - 600 $US
[PX 100] Programmabl= e extension board for microEnable=AE IV frame grabber
V-series, FPGA cop= rocessor (Xilinx XC3S1600E), 256MB DDRRAM acquisition and image processing = buffer,
digital I/O interface. Compatible with mE4 VD1-CL and mE4 = VD4-CL

PixelPlant PX200 - 1200 $US
[PX 200] Programmable extensio= n board for microEnable=AE IV frame grabber
V-series, FPGA coprocessor (= Xilinx XC3S4000), 512MB DDRRAM acquisition and image processing buffer,
= digital I/O interface. Compatible with mE4 VD1-CL and mE4 VD4-CL

I would guess that we will eventually want to use some of these cards in o= ur application, but probably not in the host that holds the framegrabber.
