Abstract:
The fixed width character generat ion is usL>aI pract ice in
the computer display system. But most of world's living languages are
of complex and composite characteristics. In this regard the variable
width character gener~tion and Display has significant effect on the
Computer system. In our country research works in this field is in the
prel iminary stage.
Uti Iizing bit-mapped graphics characters of any shape may be
formed. But it results in a slow and .cumbersome process. Attempts
are going on to make hardware-based system. A hardware-based system
alleviate this problem by scanning and addressing each dot and becomes
optimized for real~-time appl ication.
The present work deals with the development of hardware" basedsystem.
By carefully analyzing the requirements, choosing acceptable
representation scheme of characters, selecting different microprocessorbased
logic modules, the system has been designed. It can handle a
character of unit matrix to maxm of 8x7 matrix. Actually the coding
scheme of characters determine the generation of its bit-pattern
matrices. The proposed system is capable of displaying al I kinds of
variable width complex and composite characters in a aesthetic and
legible manner.
