Abstract: A self correcting device includes a first flip-flop to receive data and coupled to a clock input; one or more delayed flip-flops used to detect delay variations; a multiplexer coupled to the output of the first flip-flop and the delayed flip-flops, a metastability detector and error check controller to control the multiplexer to select one flip-flop output; and an adaptive voltage swing link coupled to the multiplexer output to generate a voltage swing on the link based on a selected clock skew.

Abstract: The invention is an efficient system and method for re-partitioning an existing system-level design by boosting the fraction of system functionality that is implemented using embedded software. The invention comprises automated techniques for identifying hardware targets to be softened and techniques for automatically generating a new system-level architecture having a new hardware/software boundary.

Abstract: Systems and methods are provided for annotating software with performance information. The computer code is compiled into assembler code, the assembler code is translated into a simulation model, expressed in assembler-level source code. The simulation model is annotated with information for calculating various performance parameters of the software, such as timing information, or resource usage information. The simulation model is then re-compiled and executed on a simulator, optionally including a hardware simulation model, and the performance information is computed from the simulation.

Abstract: This paper presents a methodology for designing System-On-Chip interconnection architectures providing a high level of protection from crosstalk effects. An event driven simulator enriched with fault injection capabilities is exploited to evaluate the dependability level of the system being designed. The simulation environment supports several bus coding protocols and thus designers can easily evaluate different design alternatives. To enhance the dependability level of the interconnection architecture, we propose a distributed bus guardian scheme, where dedicated hardware modules monitor the integrity of the information transmitted over the bus and provide error correction mechanisms.
