Networks-on-Chip are seen as promising interconnect solutions, offering the advantages of scalability and high frequency operation which the traditional bus interconnects lack. Several NoC implementations have been presented in the literature, some of them having mature tool-flows. The main differentiating factor between the various implementations are the(More)
Time-division-multiplexed networks based on the contention-free routing model represent an attractive high-performance and low-cost solution for on-chip communication thanks to their low buffer requirements at the router level. Traditionally, allocating the slots for each connection in the network TDM tables was performed at design time, thus requiring(More)
Networks-on-Chip are seen as promising interconnect solutions, offering the advantages of scalability and high frequency operation which the traditional bus interconnects lack. Several NoC implementations have been presented in the literature, some of them having mature tool-flows and ecosystems. The main differentiating factor between the various(More)
Networks on chip have evolved as the natural solution for a scalable interconnect that can be automatically generated to suit the needs of the desired application. In this study we focus on improving the efficiency of on-chip networks using alternative routing strategies. We focus on a multi-path slot allocation method in networks with static resource(More)
This paper examines the opportunity of using compression for accelerating the (re)configuration of FPGA devices, focusing on the choice of compression algorithms, and their hardware implementation cost. As our purpose is the acceleration of the configuration process, estimating the decoder speed also plays a major role in our study. We evaluate a wide range(More)
Multi-processors systems on chip (MPSOC) platforms emerged in embedded systems as hardware solutions to support the continuously increasing functionality and performance demands in this domain. Such a platform has to execute a mix of applications with diverse performance and timing constraints, i.e., real-time or non-real-time, thus different application(More)
Systems-on-Chip (SoC) complexity increases as a growing number of applications are integrated and executed on contemporary systems. These applications consist of communicating tasks mapped on heterogeneous multi-processor platforms with distributed memory hierarchies that strike a good balance between performance, cost, power consumption and flexibility(More)
Title: Network-on-chip security using multipath routing Authors: Radu Stefan, Kees Goossens keywords: noc, multipath, security In a highly competitive consumer electronics industry, companies try to protect their IP and that of their customers from reverse-engineering attempts and sometimes they attempt to crate barriers against unauthorized use of their(More)
After gaining popularity as a method of authentication in the form of smart cards, electronic security mechanisms are making their way into the domain of embedded domain with the goal of protecting Intellectual Property or for Digital Rights Management. A key role in implementing security at chip-level is played by the interconnect, which has the task of(More)
