Pipelined processor for vector data classification according to vector attributes using coupled comparator chain and logic gate to respective bin chain

摘要

A classification processing unit is disclosed for use with a computer having a register for storing classification data items and for storing data items respectively associated with the classification data items. The classification processing unit includes a comparator for receiving the classification data items from the register, which has an array of comparator units, each unit having a reference value for comparison with the classification data items. The processing unit also includes a classification pipline having an array of classification units respectively associated with the comparator units. The classification pipeline receives data items respectively associated with the classification data items and stores the data items respectively associated with said classification data items into the register in response to trigger signal from the comparator. The processing unit further has a counter provided for each of the classification units to count the number of data items that are stored by the processing unit.
