Abstract

As multicore processors find increasing adoption in domains such as aerospace and medical devices where failures have the potential to be catastrophic, strong performance isolation and security become first-class design constraints. When cores are used to run separate pieces of the system, strong time and space partitioning can help provide such guarantees. However, as the number of partitions or the asymmetry in partition bandwidth allocations grows, the additional latency incurred by time multiplexing the network can significantly impact performance.
