On-chip ring network designs for hard-real time systems
Abstract
Rings have been extensively used in high-performance systems to improve performance and scalability, and to reduce cost, energy and design effort. However, in the real-time domain, they have not been thoroughly analyzed to provide worst-case time bounds. We propose several on-chip ring designs in shared-memory multicore processors that enable the computation of trustworthy upper bounds to the time required for a packet to traverse the ring, which is a fundamental requirement to enable their use in real-time systems. © 2013 ACM.
