specific Embodiment approach

[0016] Specific embodiments are as follows.

[0017] A method for dynamic reconfiguration of a spaceborne computer based on task adaptive allocation, which is used for task adaptive allocation and dynamic reconfiguration among different CPUs inside the spaceborne computer. Including the following steps:

[0018] Step 1. Task assignment state initialization. The schematic diagram of the task allocation state initialization process is as follows: figure 1 As shown, the specific process is as follows:

[0019] (1) Each CPU sets its working mode to initialization mode, and initializes the communication driver module, and establishes a hardware channel connection for communication between CPUs. In this embodiment, the ARINC659 bus is used as the hardware channel for communication between CPUs, the ARINC659 bus communication driver module is designed, and it is hooked into the operating system, and then the system call of the operating system is called to create a CPU communicat...

Abstract

The invention discloses an on-board computer dynamic reconstruction method and system based on task self-adaptive allocation. The method comprises the following steps: sending heartbeat information between CPUs, initially setting a system working mode according the heartbeat information and the own CPU identifier; and realizing the independent switching of the system working mode and the dynamic allocation and creation of the task by monitoring the periodic heartbeat information. Through the method disclosed by the invention, each CPU can restart the work task according to the working mode andthe own CPU identifier, and supports the creation and the starting of the expansion task; the capacity of processing the task amount by the system is increased, the system flexibility is strong, thesoftware function of the on-board computer can be dynamically expanded according the task demand in the on-orbit running period of the spacecraft, and the computing capacity and the reliability of thesystem are improved.

Description

technical field [0001] The invention relates to a method and system for dynamic reconfiguration of a spaceborne computer based on task self-adaptive allocation, and belongs to the field of spacecraft integrated electronics technology. Background technique [0002] In order to improve the reliability, the on-board computer in the traditional spacecraft generally adopts a two-computer or three-computer mode, and the two-computer generally adopts the cold standby mode, and each single computer includes a processor (CPU) module and several IO modules. CPUs cannot communicate, and a single CPU cannot access the IO module of another single machine. [0003] Above-mentioned design has following shortcoming: [0004] (1) The two single machines in the dual machine are in a state of full backup, and the tasks completed by each single machine are exactly the same. When the processing capacity of the single machine is limited and the tasks of the spacecraft increase greatly, it is imp...
