Superconducting System Architecture Using Wheel Based Structures

Technology Summary


This technology comprises a novel microprocessor and memory system architecture based on energy efficient rapid single flux quantum (ERSFQ) technology. A novel wheel structure is invented to enable search and multi-porting capabilities. The wheel structure, used to implement the register file, the store queue, and the MSHRs, significantly reduces the area overhead required to access and control typical CPU blocks. A memory subsystem is presented that leverages CMOS-based DRAM at cryogenic temperatures. An asymmetric memory bus with a simplified DRAM command scheme is invented to deliver sufficient bandwidth under a constrained power budget.
