Speed-Up Robust Feature (SURF) is an effective algorithm for feature extraction. We propose a novel Scaled-RAM Interpolator (SRI) on FPGA to deal with the high complexity of SURF by introducing two methods. 1) Interpolation of Integral Image (I3) restores the sub-pixel details of image to improve matching precision, and halves the memory access to achieve acceleration; 2) Multi-Scaled RAM (MSR) normalizes...
Vertex-centric graph computations are widely used in many machine learning and data mining applications that operate on graph data structures. This paper presents GraphGen, a vertex-centric framework that targets FPGA for hardware acceleration of graph computations. GraphGen accepts a vertex-centric graph specification and automatically compiles it onto an application-specific synthesized graph processor...
In many application domains, data are represented using large graphs involving millions of vertices and billions of edges. Graph exploration algorithms, such as breadth-first search (BFS), are largely dominated by memory latency and are challenging to process efficiently. In this paper, we present a reconfigurable hardware methodology for efficient parallel processing of large-scale graph exploration...
In order to reduce test and repair cost in advanced system-on-chip products, wireless built-in self-repair (BISR) techniques for embedded memories are proposed in this paper. The redundant memory is divided into spare rows, spare column group blocks, and spare words which are used to replace faulty cells in the main memory. Based on this redundancy architecture, a BISR scheme suitable for built-in...
