本文介绍了KSJ—2730压缩型32位超级小型计算机的I/O外围设备控制器(以下简称MIC)的设计。MIC以位片微机(Am2901)为核心构成,支持四种接口功能:8路异步串行多路转换接口,一路同步串行接口,一路16位并行接口和一个行打接口。由于采用了微处理器与可编程阵列逻辑(PAL)以及微码等先进设计技术,使MIC的全部功能得以在一块22×39cm~2的PCB上实现。本文讨论了MIC的实现方案,给出了系统构成和微码结构,简述了其实现情况.MIC板已提供使用,运行良好。
This article describes the KSJ-2730 compact 32-bit super small computer I / O peripheral device controller (hereinafter referred to as MIC) design. MIC to bit slice microcomputer (Am2901) as the core structure, supports four interface functions: 8 asynchronous serial multiplexer interface, all the way to synchronous serial interface, all the way to 16 parallel interface and a line interface. Thanks to advanced design techniques such as microprocessors and programmable array logic (PAL) and microcode, all of the MIC functions can be implemented on a single 22 x 39 cm ~ 2 PCB. This article discusses the implementation of the MIC, given the system structure and microcode structure, briefly describes its implementation .MIC board has been provided, and works well.
