MULTIPLEXING PARALLEL PROCESSING METHOD FOR LEFT-TO-RIGHT TYPE HIDDEN MARKOVIAN MODELLING METHOD

摘要

PURPOSE: To realize a real-time processing for speech recognition or graphic recognition, etc., by avoiding any unwanted calculation processing. ;CONSTITUTION: No unwanted calculation processing is present since established parameters to all the state numbers are not '0' by calculating the probability parameter in respect to one state number corresponding to all the model numbers and calculating the established parameters in parallel to N probability models with the N processing elements. Such a processing is applied to the forward pass algorithm, backward pass alogorithm and Viterbi scoring of a forward/backward procedure. Thus, since no idle processing element is present and processing steps are reduced, parallel efficiency is improved.;COPYRIGHT: (C)1993,JPO&Japio
