Multistage front end processor system which uses either a stand- alone pre-processor or a composite pre-processor composed of serially connected stand-alone processors

摘要

A multistage front end processor system combining a plurality of front end processors serially for executing complicated pre-processing. The plurality of stand-alone front end processors (6-1 to 6-n) are programs such as a penned character recognition program and a kana-kanji conversion program. A definition information storage module (7) may contain definition information on a composite front end processor composed of a plurality of stand-alone front end processors connected serially. A control module (9) references a definition information storage module (7) and, when a composite front end processor to be started is composed, for example, of a first-stage and a second-stage stand-alone front end processors (6-1, 6-2), sends data entered from an input device 1 to the first-stage stand-alone front end processor (6-1), sends its output to the second-stage stand-alone front end processor (6- 2), and sends its output to an application program 10.
