A hallmark of the Snowmass update is Teds custom coded upsampling algorithm that replaces the stock Xilinx upsampling algorithm.

"Yes, until now I’d been using the stock upsampler/downsampler that Xilinx provides. It’s a pretty nice piece of software and does most things very well. Still I wanted better control of when things happened and since I know far more about what my filtering needs are than it does, I can save some work in places and do more in others to get a better result. To be clear we’d get the same mathematical answers with the same filters and inputs, but I’m doing some things their software wouldn’t handle."
