Abstract
The objective of the hybrid technology multithreaded architecture (HTMT) research is to determine the feasibility and structure of a parallel architecture integrating the combined capabilities of semiconductor, superconductor, and optical technologies. This mix of technologies may yield operational attributes superior to those based solely on semiconductor technology. The authors present a brief overview of the crucial technology-the superconducting rapid single-flux quantum logic (RSFQ) technology, as well as the HTMT multithreaded program execution models and architecture. The HTMT approach exploits key emerging devices. Specifically, computational performance can be dramatically improved through recent advances in RSFQ technology, making 100 GHz clock rates feasible in the near future. Memory capacity may be drastically increased through a new memory hierarchy merging superconductor memory, advanced semiconductor high-density memory and future optical 3D holographic storage. Interconnection bandwidth will be greatly enhanced by means of optical networks with very high bandwidthKeywords
