We present a number of optimization techniques to compute prefix sums on linked lists and implement them on multithreaded GPUs using CUDA. Prefix computations on linked structures involve in general highly irregular fine grain memory accesses that are typical of many computations on linked lists, trees, and graphs. While the current generation of GPUs provides substantial computational power and extremely...
Sound localization systems (SLS) identify the direction of a sound source. However, most of approaches focus on near-field identification, i.e. 1~2 m. In this paper we develop a novel algorithm for far-field sound localization based on the average magnitude difference function (AMDF), thereby extending the distance to 5 m. The far-field SLS is implemented on a field programmable gate array (FPGA)...
In order to realize the adaptive signal processing in real time, a modified fixed-point LMS algorithm for implementation in hardware was proposed in this paper. Expressions of this modified fixed-point LMS algorithm were deduced from the theoretical fixed-point LMS algorithm according to rounding errors. Data problems were discussed and efficient settling methods were suggested. A modified 8-weight...
Multi-processors and the producer-consumer problem, while key in theory, have not until recently been considered structured. In fact, few futurists would disagree with the technical unification of information retrieval systems and reinforcement learning, which embodies the key principles of cryptoanalysis. Here, we concentrate our efforts on disconfirming that DHTs and semaphores can interact to solve...
