Cursive characters have the potential to be more readable, attractive, and better suited for graphic CRT terminals compared to traditional dot-matrix characters. A system utilizing cursive-type characters can achieve higher writing rates while requiring less bandwidth than those using dot-matrix-type characters. This article explores the concept of a MOS cursive-character generator, its design, and its applications.
Cursive characters offer several advantages over dot-matrix characters, including:
A MOS cursive-character generator can be designed to produce x, y, and z analog signals for forming cursive characters with the deflection system of a CRT. The circuit design can be implemented on a single MOS integrated circuit, accepting 7-bit ASCII code and outputting x, y, and z analog signals to generate any one of 32 standard ASCII characters in 5 μs.
The MOS cursive-character generator has several key features, including:
The entire 32 character digital and analog function has been implemented on a single self-contained 16-pin silicon-gate MOS chip, 125 X 165 mil in size. Character encoding on the chip is accomplished in one mask at the diffusion step, and a straightforward mask-generation procedure has been developed. The MOS cursive-character generator has potential applications in graphic CRT terminals, display systems, and other devices that require high-quality character generation.
The MOS cursive-character generator is a significant innovation in character generation technology, offering improved readability, aesthetic appeal, and reduced bandwidth requirements. Its design and implementation on a single MOS integrated circuit make it an economical and efficient solution for various applications.
