AbstractA new instrument for conducting astronomical searches for nanosecond-scale optical pulses has been designed, built, and is now operating at Oak Ridge Observatory in Harvard, MA. The Advanced All-sky Camera, based on the previous generation ASIC-based design, is implemented using Xilinx Virtex-5 LX110 FPGAs to create a flexible and configurable system. Each FPGA has 32 1.5 Gsps analog-to-digital converters, implemented as 8-level flash ADCs using 256 of the Virtex-5's LVDS input pairs. Thirty-two FPGAs in the system total 1024 ADC channels, each with 8kB of sample memory, for triggering on and recording coincident pulse waveforms from an array of 1024 photomultiplier tube anodes.
