Keystone Research Overview
General OverviewOur recent focus has been on the design and analysis of non-traditional computing systems (including optoelectronic, parallel, and reconfigurable architectures); analog and digital VLSI design (in CMOS, SiGe, SoS and SoI technologies); and computer aided design methodologies (multi-domain mixed-signal simulation, high-level synthesis, and formal and temporal verification). Recent funding has been in the areas of multi-domain, mixed signal modeling and simulation environments, high speed electrical interconnect, and photonic circuits implemented in SiGe.
ChatoyantChatoyant is a multi-level simulation environment that supports the design and analysis of multi-domain micro-systems. These include systems that span electronics and mechanics (MEMS) as well as opto-electronics (OMEMS).
Differential signaling techniques provide high speed at the expense of "two wires per bit" for information transfer. Multi-bit differential signaling amortizes the cost of a reference value across all the information bits by the use of balanced codes.
Opto-Electronic Computer Architecture and Design
The fundamental advantages of optics as a communications medium for information processing is not in the "speed of light," but rather the unique qualities of light in its non-interference, low temporal dispersion and information capacity. The use of both free-space and guided wave optics provide many opportunities for improving the connectivity and functionality of future computing systems.
VLSI Computer Aided DesignDesign Automation is essential for the development of modern digital systems. Computer aided design encompasses the design capture, simulation, synthesis, analysis, and testing of complex systems.
Learning and PredictionThe phenomena of spatial and temporal locality in the behavior of executing programs enable the prediction of both data access patterns and data values. In a similar way, communications patterns in communicating parallel computers can be predicted and hardware resources can be optimized to minimize communication latency.
The Keystone Design Group works in both Benedum Hall and Sennott Square.
