Dynamic task mapping for mpsocs
WebComparing a single-task to the multi-task mapping, the energy spent in the NoC is reduced in average by 51% (best case: 72%), with an average execution time overhead of 18%. … WebIn this section, we describe the big-little type MPSoCs, ex-ploit the power features, and establish a guideline for suitable migration points for migrating tasks to cores. The big-little type MPSoCs are composed of multiple HP cores and LP cores. In a typical big-little MPSoC, a HP core and LP core are configured in a pair, but are activated

WebJan 1, 2014 · A critical task for recent MPSoCs design is the minimization of the consumed energy. We start from a well-characterized task graph, a direct acyclic graph representing a functional abstraction of the application that will run on the MPSoC. Each task is characterized by the number of clock cycles used for its execution. WebIn this work, we propose a new approach, that relies on the PBIL algorithm, for the mapping of tasks called Virtual Regions PBIL (VRPBIL-NoC). This strategy consists of dividing the platform into virtual regions in order to improve the search of quality solutions.
WebMar 14, 2024 · In this paper, an online task scheduling and mapping method based on a fuzzy neural network (FNN) learned by an evolutionary multi-objective algorithm (NSGA-II) to jointly optimize the main design challenges of heterogeneous MPSoCs is proposed. In this approach, first, the FNN parameters are trained using an NSGA-II-based … Webrandom tasks modeling technique proposed in our work is similar to their approach. The idea of scaling voltage of a task by exploiting its timing slack for energy reduction is not new. The technique presented in [10] proposes dynamic voltage scaling of a microprocessor under variable workloads, while the work of [7] used a voltage scaling technique
WebEvaluation of static and dynamic task mapping algorithms in NoC-based MPSoCs Abstract: Task mapping is an important issue in MPSoC design. Most recent mapping algorithms perform them at design time, an approach known as static mapping. Nonetheless, applications running in MPSoCs may execute a varying number of … WebFigure 5.
