Abstract |
Field Programmable Gate Arrays (FPGAs) are well-knownplatforms for implementing embedded systems due toconfigurability. Recently, high temperature of FPGAs is becominga serious issue due to their higher logic density, clock frequency,and complexity. In this work we propose, implement, andevaluate an embedded system with a thermal aware operatingsystem on the virtex-5 FPGA. It measures the temperature of thedevice using the system monitor IP core configured in the operatingsystem and manages the temperature, not to violate threshold,using the task suspension feature of the operating system. Aresident task in the operating system regularly checks the temperatureof the device and does thermal management if neededby suspending other active tasks for a specified time slot. If thistime slot is correctly chosen, the method degrades performanceonly 7 percent while the temperature threshold is not violated. |
