Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0019] An event tracking synchronization method based on TMS320C6678 distributed system, such as figure 1 shown, including the following steps:

[0020] Step S100, the system is powered on and initialized;

[0021] Power on the distributed system based on C6678, the chip starts RBL, and completes the system initialization configuration. This stage is a factory-fixed program and cannot be modified; guide the DSP to enter secondary loading (IBL). Since the same power supply is used, each C6678 is powered on. The initialization startup time is basically the same (tested, the difference is at the us level), and the RBL and IBL of the DSP are exactly the same, so the running time is also the same.

Abstract

The invention relates to the field of TMS320C6678 chips, in particular to an event tracking synchronization method based on a TMS320C6678 distributed system, system time synchronization of a core 0 is completed by starting a counter of the core 0 in the initial stage of power-on, so that counting time of each DSP in the system is synchronous at the moment, and time synchronization is achieved. And then other cores are synchronized by blocking the other cores at the same position, and then the other cores are started to count, so that the synchronization of all the cores is accurately and stably realized, the adaptability is strong, the system occupation is small, and the use is convenient.

Description

technical field [0001] This application belongs to the field of TMS320C6678 chips, and in particular relates to an event tracking synchronization method based on a TMS320C6678 distributed system. Background technique [0002] C6678 is a high-performance multi-core DSP embedded chip, which is widely used in the field of signal and information processing with relatively high computing requirements. TI provides a variety of C6678 loading methods, such as JTAG (test interface for debugging), Ethernet (Ethernet, referred to as ETH), PCIe (PCI Express bus) and other interfaces to load software. The Bootload of C6678 is divided into two levels. The first level is Rom Bootloader (RBL), which is a piece of code that runs first after the processor is powered on and reset. It is used to complete the system initialization configuration after the processor is powered on. How to run the second level Bootloader . The RBL code has been solidified in the processor and cannot be changed by ...
