Accurate Measurement of Power Consumption Overhead During FPGA Dynamic Partial Reconfiguration

Abstract : In the context of embedded systems design, two important challenges are still under investigation. First, improve real-time data processing, reconfigurability, scalability, and self-adjusting capabilities of hardware components. Second, reduce power consumption through low-power design techniques as clock gating, logic gating, and dynamic partial reconfiguration (DPR) capabilities. Today, several application, e.g., cryptography, Software-defined radio or aerospace missions exploit the benefits of DPR of programmable logic devices. The DPR allows well defined reconfigurable FPGA region to be modified during runtime. However, it introduces an overhead in term of power consumption and time during the reconfiguration phase. In this paper, we present an investigation of power consumption overhead of the DPR process using a high-speed digital oscilloscope and the shunt resistor method. Results in terms of reconfiguration time and power consumption overhead for Virtex 5 FPGAs are shown.
