—Implementing an application on a FPGA remains a difficult, non-intuitive task that often requires hardware design expertise in a hardware description language (HDL). High-level synthesis (HLS) raises the design abstraction from HDL to languages such as C/C++/Scala/Java. Despite this, in order to get a good quality of result (QoR), a designer must carefully(More)
We present RIFFA 2.1, a reusable integration framework for Field-Programmable Gate Array (FPGA) accelerators. RIFFA provides communication and synchronization for FPGA accelerated applications using simple interfaces for hardware and software. Our goal is to expand the use of FPGAs as an acceleration platform by releasing, as open source, a framework that(More)
—Embedding real-time 3D reconstruction of a scene from a low-cost depth sensor can improve the development of technologies in the domains of augmented reality, mobile robotics, and more. However, current implementations require a computer with a powerful GPU, which limits its prospective applications with low-power requirements. To implement low-power 3D(More)
Field Programmable Gate Array (FPGA) implementations of sorting algorithms have proven to be efficient, but existing implementations lack portability and maintainability because they are written in low-level hardware description languages that require substantial domain expertise to develop and maintain. To address this problem, we develop a framework that(More)
A common type of triangulation-based active 3D scanner outputs sets of surface coordinates, called profiles, by extracting the salient features of 2D images formed from an object illuminated by a narrow plane of light. Because a conventional 2D image must be digitized and processed for each profile, current systems do not always provide adequate speed and(More)
