The advancement in process technology has enabled integration of different types of processing cores into a single chip towards creating heterogeneous Multiprocessor Systems-on-Chip (MPSoCs). While providing high level of computation power to support complex applications, these modern systems also introduce novel challenges for system designers, like managing a huge number of mappings (application...
Simulation-based Design Space Exploration (DSE) to evaluate all possible mappings for a given application and Multiprocessor-System-on-Chip (MPSoC) platform is computationally costly for large problems. Even using efficient exploration methodologies to evaluate the mappings cannot overcome the evaluation time bottleneck. This paper presents a novel DSE methodology that analyzes the execution trace...
Dynamic voltage and frequency scaling (DVFS) offers great potential for optimizing the energy efficiency of Multiprocessor Systems-on-Chip (MPSoCs). The conventional approaches for processor voltage and frequency adjustment are not suitable for streaming multimedia applications due to the cyclic nature of dependencies in the executing tasks which can potentially violate the throughput constraints...
Real-time multi-media applications are increasingly mapped on modern embedded systems based on Multiprocessor Systems-on-Chip (MPSoCs). Tasks of the applications need to be mapped on the MPSoC resources efficiently in order to satisfy their performance constraints. Exploring all the mappings, i.e. tasks to resources combinations exhaustively may take days or weeks. Additionally, the exploration is...
