We address the problem of analyzing the performance of System-on-chip (SoC) architectures in the presence of variations. Existing techniques such as gate-level statistical timing analysis compute the distributions of clock frequencies of SoC components. However, we demonstrate that translating component-level characteristics into a system-level performance distribution is a complex and challenging...
Manufacturing and operation-induced variations have emerged as a critical challenge in designing integrated circuits (ICs) under the nanometer technology regime. Most work on addressing variations has focused on device, circuit, and logic-level solutions. As the magnitude of parameter variations increases with technology scaling, these techniques are not sufficient to address the negative impact that...
Evaluation of software performance on a given customized embedded processor is an important step in the design space exploration of embedded system architectures. Such evaluations help system designers in taking early design decisions regarding the hardware architecture most suitable for the target application. Simulation based performance evaluations, although very accurate, can be prohibitively...
The on-chip communication architecture is a primary determinant of overall performance in complex system-on-chip (SoC) designs. Since the communication requirements of SoC components can vary significantly over time, communication architectures that dynamically detect and adapt to such variations can substantially improve system performance. In this paper, we propose Flexbus, a new architecture that...
