第 9 章 TMS320C54x 硬件设计及接口技术. DSP 硬件设计是 DSP 应用系统设计的基础。 一个 DSP 最小系统 是由内部硬件资源如 CPU 、片内外设、存储器（ ROM 、 RAM 或 FLASH ）和 最基本的外围辅助电路 （ 电源、时钟晶振、复位电路和仿真接口 JTAG ）组成。 一般的实际应用系统 是由最小系统和输入输出接口、通信接口、人机交互接口、外部程序存储器或数据存储器等外围扩展电路组成。. 第 9 章 TMS320C54x 硬件设计及接口技术. 目录 9.1 基于 C54x 的 DSP 最小系统设计 9.2 C54x 外部总线结构 - PowerPoint PPT Presentation
