Proceedings ArticleDOI
Addressing Manufacturing Challenges with Cost-Efficient Fault Tolerant Routing
Samuel Rodrigo,Jose Flich,Antoni Roca,Simone Medardoni,Davide Bertozzi,J. Camacho,Federico Silla,José Duato +7 more
TL;DR: Universal Logic-Based Distributed Routing (uLBDR) as mentioned in this paper is an efficient logic-based mechanism that adapts to any irregular topology derived from 2D meshes, being an alternative to the use of routing tables.
Journal ArticleDOI
Cost-Efficient On-Chip Routing Implementations for CMP and MPSoC Systems
Samuel Rodrigo,Jose Flich,Antoni Roca,Simone Medardoni,Davide Bertozzi,Jesús Camacho,Federico Silla,José Duato +7 more
TL;DR: ULBDR is presented, an efficient logic-based mechanism that adapts to any irregular topology derived from 2-D meshes, instead of using routing tables, that requires a small set of configuration bits, thus being more practical than large routing tables implemented in memories.
Proceedings ArticleDOI
Ring Oscillator Clocks and Margins
TL;DR: The paper concludes that a synchronous circuit with a ring oscillator clock shows similar benefits in performance and energy as those of bundled-data asynchronous circuits.
Proceedings ArticleDOI
Improving the Performance of GALS-Based NoCs in the Presence of Process Variation
TL;DR: A novel approach, called performance domains, intended to reduce the negative impact of variability on application execution time is drafted, suitable when several applications are simultaneously running in the CMP chip.
Journal Article
Improved pixel-based rate allocation for pixel-domain distributed video coders without feedback channel
TL;DR: In this article, a rate allocation algorithm for pixel-domain distributed video (PDDV) coders without FBC is proposed, which estimates at the encoder the number of bits for every frame without significantly increasing the encoding complexity.
