  2. Software Design • Designed around • Existing re-usable systems • Additional elements for DU-GALL • LGS and NGS RTC systems: • Based on SPARTA • Interface to Observatory Systems: • Based on GLAS • Modular and easily reconfigurable • Hardware abstracted FPGA code • Middleware: ORB based (EG CORBA, PYRO) DU-GALL - Durham 3 April 2007

  3. SPARTA Systems • FPGA Based COTS hardware • PCI FPGA cards – HOT - Linux • VSX FPGA cards – SPARTA - VxWorks • FPGA Core: Serial Front Panel Data Protocol • Transfer speeds up to 2.5 Gbit • FPGA core: Wavefront Processing Unit (WPU) • FPGA core: Reconstructor (New) DU-GALL - Durham 3 April 2007
