Embodiment Construction

[0020] refer to figure 1 . The specific steps of the partition scheduling method under the Windows operating system environment of the present invention are as follows:

[0021] Step 1: Load the XML configuration file, read the tags and attributes of the XML file, and parse the XML configuration file. Obtain the configuration information related to scheduling and partition in the configuration file. It includes module configuration information, partition configuration information, pseudo partition configuration information, queue port configuration information, sampling port configuration information, and scheduling module configuration information. The configuration information of the scheduling module also includes main time frame configuration information, scheduling ID number, and scheduling priority information.

[0022] Specifically, load the XML configuration file, parse the XML, and read the configuration information therein. According to the information in the XML...

Abstract

The invention discloses a method for partition scheduling in a Windows operating system environment, and the method is used to solve the technical problem that an existing partition scheduling method is low in practicality. The technical scheme is that by using affinity setting of the Windows system, CPU (Central Processing Unit) resources of the system are reallocated, and a running core of a real-time task is appointed, so that resources needed by the real-time task can be ensured; a two-level scheduling model is adopted, wherein the model comprises two levels of schedulers: a module scheduler of a scheduling partition, and a partition scheduler of a process in the scheduling partition; and a secondary scheduling model is inclined to a cycle round-robin scheduling partition of the module scheduler, and the partition scheduler preempts a scheduling process based on a fixed priority. According to the scheduling method, in the Windows environment, a virtual two-level scheduling policy of ARINC 653 is created, thereby providing a good development and debugging environment for embedded software; and the method is high in practicality and reduces development cost.

Description

technical field [0001] The invention relates to a partition scheduling method, in particular to a partition scheduling method under the Windows operating system environment. Background technique [0002] The real on-board operating system needs to run on a real aircraft. However, running on a real hardware platform will bring great inconvenience to the development and testing of application software. The virtual simulation verification platform has become a current research hotspot. The avionics simulation system is the product of the combination of simulation technology and avionics system. It mainly conducts comprehensive system analysis, program design and performance evaluation on the development, measurement and control, management and application of airborne avionics systems. [0003] The more mature avionics simulation real-time operating system in foreign countries is Vxworks of American WindRiver Company. However, the airborne operating system can only be simula...
