Abstract
A fast and intelligent character recognition system is developed for
application towards automatic recognition.
As an important part of the system, a fast character
recognition subsystem based on systolic architecture is developed.
In this paper, systolic architecture is proposed, which is
used to develop the subsystem.
And the implemented hardware, called an image processor, is described.
The image processor is designed to process at a rate of about 500 characters
per second.
The proposed architecture is a parallel processor that preprocess
character images in a pipeline manner, and then invokes
a recognition algorithm called associative matching, which is a
pattern matching algorithm improved to work faster.
