In current Systems-on-Chip (SoC) designs, managing peak temperature is critical to ensure operation without failure. The authors' novel Communication architecture Based Thermal Management (CBTM) scheme manages thermal behavior of components by delaying the execution of chosen IP-blocks or components by regulating the flow of data over the on-chip communication bus. This temperature aware traffic flow over the bus is achieved by dynamically changing the communication priority table in response to thermal readings from sensors. With CBTM, the temperatures of individual components can be controlled selectively.
