片外在线可编程的soc系统及其控制方法

Off-chip online programmable SOC (system on a chip) and control method for same

Abstract

本发明涉及SOC设计技术领域,特别是一种片外在线可编程的SOC系统及其控制方法,该系统包括SOC芯片、片外Nflash/Norflash以及片外开关,所述SOC芯片由SOC最小系统、串口控制器、Nflash/Norflash控制器和复位控制CCU模块组成,所述SOC最小系统包括CPU、内部存储器和片内总线;该系统的控制方法为:在计算机上完成软件编译,通过片外开关的选择控制,将SOC系统切换到编程模式,将编译的可执行文件数据下载到片外Nflash/Norflash存储器中,然后再切换到正常工作模式,进行系统运行。该系统及其控制方法不仅有利于软件系统的开发,而且易于调试,调试过程芯片不易损坏。
The invention relates to the technical field of design of an SOC (system on a chip), in particular to an off-chip online programmable SOC (system on a chip) and a control method for the same. The system comprises an SOC, an off-chip Nflash/Norflash storage and an off-chip switch, the SOC comprises a minimum SOC, a serial port controller, an Nflash/Norflash controller and a reset control CCU (central control unit) module, and the minimum SOC comprises a CPU (central processing unit), an internal storage and an on-chip bus. The control method for the system includes: compiling software on a computer, switching the SOC into a programming mode by means of selection control of the off-chip switch, downloading compiled executable file data into the off-chip Nflash/Norflash storage, and then switching the SOC into a normal operating mode to realize system operation. The system and the control method for the system are not only beneficial to development of a software system, but also easy to debug, and the chip is not easy to damage during debugging.
