Abstract

A 16-bit control word is disclosed for use in character recognition. By using 16 bits in the manner disclosed, instead of the typical 8-bit control word, the overhead storage requirements for implementing tree logic in character recognition systems is greatly reduced. The 16-bit control word operates as a test-type control word and includes the data buffer byte offset of the byte to be tested, or it operates as an exit- type control word and includes the location of the next control word for the decision tree logic. The architecture of these 2-byte control words is shown in the figure, including an example for a tree logic. The caption beneath the figure describes the information contained in each of the bits 13 - 15, depending upon whether the control word is a test control word or an exit control word.
