Abstract

Megacam is a wide-field optical imager for the converted MMT that uses thirty-six 2048 by 4608 pixel CCDs to cover a 24' X 24' format. We describe a computer architecture designed to accommodate the expected data volume and show benchmark results from prototype implementations that demonstrate the performance attained by each of the design decisions. We show that our time budget allotments can be met using a modular, scalable architecture design that exploits the natural parallelization of multiple, identical detector components.
