We propose a novel Viterbi processor for the large vocabulary real-time continuous speech recognition. This processor is built with multi Viterbi cores. Since each core can independently compute, these cores reduce the cycle times very efficiently. To verify the effect of utilizing multi cores, we implement a dual-core Viterbi processor in an FPGA and(More)
SUMMARY This paper describes a SIFT (Scale Invariant Feature Transform) descriptor generation engine which features a VLSI oriented SIFT algorithm, three-stage pipelined architecture and novel systolic array architectures for Gaussian filtering and key-point extraction. The ROI-based scheme has been employed for the VLSI oriented algorithm. The novel(More)
