片上双系统总线设计及其应用

Design and Application of Dual System-Bus Architecture

本文设计了基于AM BA总线结构的双系统总线结构,其最大特点是APB系统能够独立于高速数据传输的AH B系统,实现对AH B系统的控制和对A PB低速外设的操作,大大提高了系统的性能和灵活性。文中详细介绍了此设计的实现,并给出了双系统总线结构在苏州国芯科技的C*SO C-A项目的应用实例。

A design of a dual-system-bus architecture based on AMBA . In this architecture, the APB and AHB subsystems operate completely independent of each other. The MCU in the APB subsystem controls the high-speed data transfer of AHB subsystem and the low-speed APB peripheries. This paper introduces the detail of this design, and also give an example which implements the dual-system-bus architecture in C*SOC-A project in C*Core Corp Suzhou.
