REMcode: relocating embedded code for improving system efficiency

REMcode: relocating embedded code for improving system efficiency - Computers and Digital Techniques, IEE Proceedings-

The memory hierarchy subsystem has a significant impact on performance and energy consumption of an embedded system. Methods which increase the hit ratio of the cache hierarchy will typically enhance the performance and reduce the embedded system’s total energy consumption. This is mainly due to reduced cache-to-memory bus transactions, fewer main memory accesses and fewer processor waiting cyc...

Improving energy efficiency for flash memory based embedded applications

The JFFS2 file system for flash memory compresses files before actually writing them into flash memory. Because of this, multimedia files, for instance, which are already compressed in the application level go through an unnecessary and time-consuming compression stage and cause energy waste. Also, when reading such multimedia files, the default use of disk cache results in unnecessary main mem...

Relocating XML Elements from Preprocessed to Unprocessed Code

Transformations performed on source code by a preprocessor complicate the accurate reporting of information extracted to support program comprehension. Differences between the file input to the preprocessor and the output seen by parser-based analyzers creates a need for techniques to back-locate extracted information. To correctly map analysis results back to the preprocessor input files requi...

MATLAB CODE FOR VIBRATING PARTICLES SYSTEM ALGORITHM

In this paper, MATLAB code for a recently developed meta-heuristic methodology, the vibrating particles system (VPS) algorithm, is presented. The VPS is a population-based algorithm which simulates a free vibration of single degree of freedom systems with viscous damping. The particles gradually approach to their equilibrium positions that are achieved from current population and historically b...
