Quantum Image Processing and Its Application to Edge Detection: Theory and Experiment

Processing of digital images is continuously gaining in volume and relevance, with concomitant demands on data storage, transmission and processing power. Encoding the image information in quantum-mechanical systems instead of classical ones and replacing classical with quantum information processing may alleviate some of these challenges. By encoding and processing the image information in quantum-mechanical systems, we here demonstrate the framework of quantum image processing, where a pure quantum state encodes the image information: we encode the pixel values in the probability amplitudes and the pixel positions in the computational basis states. Our quantum image representation reduces the required number of qubits compared to existing implementations, and we present image processing algorithms that provide exponential speed-up over their classical counterparts. For the commonly used task of detecting the edge of an image, we propose and implement a quantum algorithm that completes the task with only one single-qubit operation, independent of the size of the image. This demonstrates the potential of quantum image processing for highly efficient image and video processing in the big data era.Comment: 13 pages, including 9 figures and 5 appendixe

Survey of FPGA applications in the period 2000 – 2015 (Technical Report)

Romoth J, Porrmann M, Rückert U. Survey of FPGA applications in the period 2000 – 2015 (Technical Report).; 2017.Since their introduction, FPGAs can be seen in more and more different fields of applications. The key advantage is the combination of software-like flexibility with the performance otherwise common to hardware. Nevertheless, every application field introduces special requirements to the used computational architecture. This paper provides an overview of the different topics FPGAs have been used for in the last 15 years of research and why they have been chosen over other processing units like e.g. CPUs

Dynamic reconfiguration frameworks for high-performance reliable real-time reconfigurable computing

The sheer hardware-based computational performance and programming flexibility offered by reconfigurable hardware like Field-Programmable Gate Arrays (FPGAs) make them attractive for computing in applications that require high performance, availability, reliability, real-time processing, and high efficiency. Fueled by fabrication process scaling, modern reconfigurable devices come with ever greater quantities of on-chip resources, allowing a more complex variety of applications to be developed. Thus, the trend is that technology giants like Microsoft, Amazon, and Baidu now embrace reconfigurable computing devices likes FPGAs to meet their critical computing needs. In addition, the capability to autonomously reprogramme these devices in the field is being exploited for reliability in application domains like aerospace, defence, military, and nuclear power stations. In such applications, real-time computing is important and is often a necessity for reliability. As such, applications and algorithms resident on these devices must be implemented with sufficient considerations for real-time processing and reliability. Often, to manage a reconfigurable hardware device as a computing platform for a multiplicity of homogenous and heterogeneous tasks, reconfigurable operating systems (ROSes) have been proposed to give a software look to hardware-based computation. The key requirements of a ROS include partitioning, task scheduling and allocation, task configuration or loading, and inter-task communication and synchronization. Existing ROSes have met these requirements to varied extents. However, they are limited in reliability, especially regarding the flexibility of placing the hardware circuits of tasks on device’s chip area, the problem arising more from the partitioning approaches used. Indeed, this problem is deeply rooted in the static nature of the on-chip inter-communication among tasks, hampering the flexibility of runtime task relocation for reliability. This thesis proposes the enabling frameworks for reliable, available, real-time, efficient, secure, and high-performance reconfigurable computing by providing techniques and mechanisms for reliable runtime reconfiguration, and dynamic inter-circuit communication and synchronization for circuits on reconfigurable hardware. This work provides task configuration infrastructures for reliable reconfigurable computing. Key features, especially reliability-enabling functionalities, which have been given little or no attention in state-of-the-art are implemented. These features include internal register read and write for device diagnosis; configuration operation abort mechanism, and tightly integrated selective-area scanning, which aims to optimize access to the device’s reconfiguration port for both task loading and error mitigation. In addition, this thesis proposes a novel reliability-aware inter-task communication framework that exploits the availability of dedicated clocking infrastructures in a typical FPGA to provide inter-task communication and synchronization. The clock buffers and networks of an FPGA use dedicated routing resources, which are distinct from the general routing resources. As such, deploying these dedicated resources for communication sidesteps the restriction of static routes and allows a better relocation of circuits for reliability purposes. For evaluation, a case study that uses a NASA/JPL spectrometer data processing application is employed to demonstrate the improved reliability brought about by the implemented configuration controller and the reliability-aware dynamic communication infrastructure. It is observed that up to 74% time saving can be achieved for selective-area error mitigation when compared to state-of-the-art vendor implementations. Moreover, an improvement in overall system reliability is observed when the proposed dynamic communication scheme is deployed in the data processing application. Finally, one area of reconfigurable computing that has received insufficient attention is security. Meanwhile, considering the nature of applications which now turn to reconfigurable computing for accelerating compute-intensive processes, a high premium is now placed on security, not only of the device but also of the applications, from loading to runtime execution. To address security concerns, a novel secure and efficient task configuration technique for task relocation is also investigated, providing configuration time savings of up to 32% or 83%, depending on the device; and resource usage savings in excess of 90% compared to state-of-the-art

This document is an update (new photos used) of the PDF version of the 2020 NASA Technology Taxonomy that will be available to download on the OCT Public Website. The updated 2020 NASA Technology Taxonomy, or "technology dictionary", uses a technology discipline based approach that realigns like-technologies independent of their application within the NASA mission portfolio. This tool is meant to serve as a common technology discipline-based communication tool across the agency and with its partners in other government agencies, academia, industry, and across the world

The NASA SBIR product catalog

The purpose of this catalog is to assist small business firms in making the community aware of products emerging from their efforts in the Small Business Innovation Research (SBIR) program. It contains descriptions of some products that have advanced into Phase 3 and others that are identified as prospective products. Both lists of products in this catalog are based on information supplied by NASA SBIR contractors in responding to an invitation to be represented in this document. Generally, all products suggested by the small firms were included in order to meet the goals of information exchange for SBIR results. Of the 444 SBIR contractors NASA queried, 137 provided information on 219 products. The catalog presents the product information in the technology areas listed in the table of contents. Within each area, the products are listed in alphabetical order by product name and are given identifying numbers. Also included is an alphabetical listing of the companies that have products described. This listing cross-references the product list and provides information on the business activity of each firm. In addition, there are three indexes: one a list of firms by states, one that lists the products according to NASA Centers that managed the SBIR projects, and one that lists the products by the relevant Technical Topics utilized in NASA's annual program solicitation under which each SBIR project was selected
