摘要
多核处理器片内一般具有容量较大的动态RAM,其程序代码存储在片外Flash中,或者通过主机下载程序。多核DSP的启动和单核启动区别较大,本文以8核DSP芯片TMS320C6678为应用平台,介绍了多核DSP的启动方法。通过I2 C总线芯片存储一级启动程序,应用程序存储到容量较大的Nand Flash芯片,文中详细介绍了该启动方法的软硬件设计。
An application program is running on RAM in multicore DSP, and it is saved in Flash outside the chip or downloaded by the host. There are great differences between multicore and single core Bootload. Using DSP chip TMS320C6678 with 8 cores as the appli cation platform, the Bootload method of multicore DSP is introduced. First boot program is stored in 12 C Flash and application programs are stored in Nand Flash. Detailed hardware and software design is given.
