ABSTRACT:

Rapid growth of power density has become a serious challenge in many-core chips, which might cause problems like temperature overhead, degraded reliability, etc.

One important component, the on-chip communication system, has a large contribution on the overall system power consumption and performance. Therefore, in this talk, we discuss how to optimize the on-chip communication system under the temperature and/or power constraints such that the communication performance is optimized. In specific, the following two topics will be covered. 1. How to route packets optimally with thermal- and congestion-awareness. 2. How to perform power budgeting under the temperature and power constraints. In these two topics, a dynamic-programming network is proposed as the optimization tool, which can solve the optimization problem optimally with low overhead and complexity.
