摘要
介绍了软驱控制器(FDC)芯片GM82C765的原理及FAT12文件系统。以TI公司的新一代高速DSPTMS320F2812为主控制器,扩展了大容量SRAM,设计了与FDC的硬件接口,在C语言环境下开发了DSP的磁盘文件操作系统,并将该系统成功应用于电脑绣花机电控系统中。同时还介绍了主要的硬件接口和软件设计思想,对寻道延时、重校验和DSP内存管理等关键问题进行了讨论。
The principle of the FDC chip GM82C765 and the FAT12 file system are discussed. The hardware interface between the FDC and the latest DSP TMS320F2812 of TI Corporation is designed. Based on C programming language, the file operation system of the DSP is developed and applied successfully in the computer embroidery machine control system. Some key problems such as seek time, recalibration, memory management etc. are discussed.
