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)
An 8-month-old cat with bilateral hindlimb paresis was admitted. Radiography revealed a curvature of the thoracic spine and a partial deformation of thoracolumbar vertebrae (dorsal extrusion of the cranial and caudal edges). Compression of the spinal cord (T9-L1 and L6-7) was found by myelography. Medicinal treatment did not yield the desired result.(More)
