A software energy estimation model is presented for a family of high performance, integrated, 32-bit embedded RISC processors. This model is significantly less complex than previous models, and yet is demonstrated to accurately predict energy consumption to within 8% with 99% confidence based on physical measurements. Factors such as operating frequency,(More)
A static performance evaluation technique is proposed to support early, architecture-level design space exploration for component-based embedded systems. The novel contribution is the use of a designer-specified evaluation scenario to identify a characteristic subset of system functionality that serves as a context for a rapid performance evaluation between(More)
Program profiling is common way to characterize program behavior based on representative input. Some software, especially in embedded systems, cannot be profiled do to lack of tools or problems introduced by instrumentation of the code. As an alternative to traditionally profiling, a static analysis technique is proposed that allows a designer to(More)
Program slicing is a software analysis technique that computes the set of operations in a program that may affect the computation at a particular operation. Interprocedural slicing techniques have separately addressed concurrent programs and hardware description languages. However, application of slicing to codesign of embedded systems requires dependence(More)
Embedded Architect is a design automation tool that embodies a static performance evaluation technique to support early, architecture-level design space exploration for component-based embedded systems. A static control flow characterization, called an evaluation scenario, is specified based on an incremental refinement of software source code, from which a(More)
