A Visual Design for Peripheral Interface Chip
Abstract
As the technology developing, the use of computer is becoming more and more widely. Due to this fact, the parallel interface which mainly used for greatly increasing speed of data transfer, has driven a lot attention. It makes the computer kits setup and use much easier, also with no number restriction. We get it worked much better in common use by studying and researching the principle of it.
In this design, take parallel 8255A chip for example, study its inner structure, understand the interface selectiveness and transmission way with CPU. Parallel interface achieve the data transmission between bit and I/O devices using more than one data wire, which is suit for short distance transmission. Come to a direct display of its functionalities with VC virtual platform by visual design.
Data and code in every computer parts, describes itself by combination, the function is invisible. By make a programmed of software on the platform, in order to show the parallel interface logic by using computer graphic technology. Also make it available for adjusting and research.
