As real-time embedded systems demand more and more computing power under reasonable energy budgets, multi-core platforms are a viable option. However, deploying real-time applications on multi-core platforms introduce several predictability challenges. One of these challenges is bounding the latency of memoryaccesses issued by real-time tasks. This challenge is exacerbated as the number of cores and, hence, the degree of resource sharing increases. Over the last several years, researchers have proposed techniques to overcome this challenge. In prior work, we proposed an arbitration policy for memoryaccess requests over a Network-on-Chip. In this paper, we implement and evaluate variants of our arbitration policy on a real hardware platform, namely Tilera's TilePro64 platform.
