I am working on a new technology: a threaded token processor that uses a sliding window to access virtually unlimited memory using only 8 bits per instruction. If you are interested, I published two articles on FPGARelated.com describing the details.

The technology has been placed into the Public Domain to assure there are no limits on usage and no one can patent it.

Feedback appreciated.
