Sparse matrix-vector multiplication (SMVM) is a fundamental core of many high-performance computing applications, including information retrieval, medical imaging, and economic modeling. While the use of reconfigurable computing technology in a high-performance computing environment has shown recent promise in accelerating a wide variety of scientific applications, existing SMVM architectures on FPGA...
Pipelining technology can improve clock frequency through shortening the critical path of logic device. However, the complex algorithm of gradient adaptive lattice joint processing (GALJP ) results in its lower work clock frequency. A pipeline optimization approach based on the technology of delay leading transfer is proposed. By approximate treatment to the updated weight coefficients and errors...
A floating-point accumulator for FPGA-based high performance computing applications is proposed and evaluated. Compared to previous work, our accumulator uses a fixed size circuit, and can reduce an arbitrary number of input sets of varying sizes without requiring prior knowledge of the bounds of summands. In this paper, we describe how the adder accumulator operator can be heavily pipelined to achieve...
This paper presents the implementation of an induction machine dynamic simulation on a field-programmable gate array (FPGA) board. Using FPGAs as computational engines can lead to significant simulation speed gains when compared to a typical PC computer, especially when operations can be efficiently parallelized on the board. The textbook example of a free acceleration followed by a step load change...
