Cursive characters have become increasingly popular in recent years due to their readability, attractiveness, and suitability for graphic CRT terminals. A system using cursive-type characters can achieve higher writing rates while requiring less bandwidth than traditional dot-matrix-type characters.
A cursive-character generator is a device or system that produces cursive characters on a graphic display, such as a CRT (cathode ray tube). These generators use a deflection system to create the x, y, and z analog signals necessary for forming cursive characters.
The benefits of cursive-character generators include:
A circuit design for a complete 48-stroke character generator on a single MOS integrated circuit has been developed. This IC accepts 7-bit ASCII code and outputs x, y, and z analog signals to generate any one of 32 standard ASCII characters in 5 μs. Additional groups of 32 characters can be added by paralleling additional chips.
The character generator has the following technical specifications:
Cursive-character generators have various applications in graphic display systems, including:
