Dynamic Partial Reconfiguration

Machine learning is widely used these days to extract meaningful information out of the Zettabytes of sensors data collected daily. All applications require analyzing and understanding the data to identify trends, e.g., surveillance, exhibit some error tolerance. Approximate computing has emerged as an energy-efficient design paradigm aiming to take advantage of the intrinsic error resilience in a wide set of error-tolerant applications. Thus, inexact results could reduce power consumption, delay, area, and execution time. To increase the energy-efficiency of machine learning on FPGA, we consider approximation at the hardware level, e.g., approximate multipliers. However, errors in approximate computing heavily depend on the application, the applied inputs, and user preferences. However, dynamic partial reconfiguration has been introduced, as a key differentiating capability in recent FPGAs, to significantly reduce design area, power consumption, and reconfiguration time by adaptively changing a selective part of the FPGA design without interrupting the remaining system. Thus, integrating “Dynamic Partial Reconfiguration” (DPR) with “Approximate Computing” (AC) will significantly ameliorate the efficiency of FPGA-based design approximation. In this article, we propose hardware-efficient quality-controlled approximate accelerators, which are suitable to be implemented in FPGA-based machine learning algorithms as well as any error-resilient applications. Experimental results using three case studies of image blending, audio blending, and image filtering applications demonstrate that the proposed adaptive approximate accelerator satisfies the required quality with an accuracy of 81.82%, 80.4%, and 89.4%, respectively. On average, the partial bitstream was found to be 28.6 smaller than the full bitstream .

As reconfigurable devices' capacities and the complexity of applications that use them increase, the need forself-relianceof deployed systems becomes increasingly prominent. Organic computing paradigms have been proposed for fault-tolerant systems because they promote behaviors that allow complex digital systems to adapt and survive in demanding environments. In this paper, we develop asustainable modular adaptive redundancy technique (SMART)composed of a two-layered organic system. The hardware layer is implemented on a XilinxVirtex-4Field Programmable Gate Array (FPGA) to provide self-repair using a novel approach calledreconfigurable adaptive redundancy system (RARS). The software layer supervises the organic activities on the FPGA and extends the self-healing capabilities through application-independent, intrinsic, and evolutionary repair techniques that leverage the benefits of dynamic partial reconfiguration (PR). SMART was evaluated using a Sobel edge-detection application and was shown to tolerate stressful sequences of injected transient and permanent faults while reducing dynamic power consumption by 30% compared to conventionaltriple modular redundancy (TMR)techniques, with nominal impact on the fault-tolerance capabilities. Moreover, PR is employed to keep the system on line while under repair and also to reduce repair time. Experiments have shown a 27.48% decrease in repair time when PR is employed compared to the full bitstream configuration case.
