This paper introduces FNOCEE, a framework for the evaluation of NoC-based many-cores systems by FPGA-based emulation. It uses a task graph-oriented approach to model applications, while a hardware-accelerated genetic algorithm is employed to find close-to-optimal solutions to the task mapping problem. The proposed genetic algorithm is analyzed in detail,(More)
Complex signal processing algorithms targeted on architectures with increasingly high numbers of parallel processing units require high performance core-interconnections (i.e., low latencies, high throughput, no pinch-offs or bottlenecks). Therefore, assisting techniques, exploring characteristics of diverse topologies of common as well as innovative(More)
Optical wireless communication (OWC) or visible light communication (VLC) has recently experienced a significant growth in interest. Due to the vast bandwidth available in the unlicensed light spectrum, the ascent of LED-based lighting, inherent security and EM benefits, OWC can be regarded as an attractive alternative to commonly available RF-based(More)
In this paper we present a simulation-based approach to determine the impact of placement and duty-cycle of wireless embedded sensor actor network (WESAN) nodes on various parameters, such as expectable lifetime, latency and overall operability. It accurately reflects hardware characteristics, e.g. power consumption, switching times, and therefore enables(More)
