Embodiment 1

[0063] Under the parallel algorithm, IO processing tasks and model tasks are executed in parallel. The output of the IO processing task can be processed by the model task after one step, and the input of the IO processing task comes from the output of the model task of the previous step, so in this mode, the output of the IO processing task and the input of the model task There will be a step delay between, such as figure 2 shown. exist figure 2 , the execution sequence is as follows:

[0064] 1) The OP1 operation completes the data reading operation from the data control layer and the input port assignment operation;

[0065] 2) The OP2 operation completes the input port value operation;

[0066] 3) The OP3 operation completes the input port assignment operation;

[0067] 4) The OP4 operation completes the value-taking operation of the output port and the data writing operation of the data control layer.

[0068] In parallel mode, the task scheduling process is as fol...

Embodiment 2

[0077] Under the serial algorithm, IO processing tasks are executed before model tasks are executed. In this mode, it can be guaranteed that the model task processes the IO data of the same step size, such as image 3 shown. exist image 3 , the execution sequence is as follows:

[0078] 1) The OP1 operation completes the data reading operation from the data control layer and the input port assignment operation;

[0079] 2) The OP2 operation completes the value-taking operation of the input port;

[0080] 3) The OP3 operation completes the input port assignment operation;

[0081] 4) The OP4 operation completes the value-taking operation of the output port and the data writing operation of the data control layer.

[0082] In serial mode, the scheduling process of the task scheduling module is as follows:

[0083] 1) Obtain all the inputs of the hardware I / O layer from the data control layer, put these inputs into the input ports of the hardware I / O layer, and then releas...

Description

technical field [0001] The invention relates to a multi-core multi-model parallel distributed real-time simulation system, which belongs to the technical field of engineering system real-time simulation. Background technique [0002] Engineering systems (including aircraft, missiles, satellites, automobiles, etc.) must undergo a large number of ground tests before the design is finalized. The external environment required for the test usually needs to be simulated in the laboratory through a hardware-in-the-loop simulation system. The real-time simulation system is usually an important part of the hardware-in-the-loop simulation system. The real-time calculation of the digital model of the physical system is realized through the real-time simulation system, and the hardware I / O is cross-linked with the external system to achieve the purpose of the hardware-in-the-loop simulation test. [0003] As the complexity of the engineering system increases, the complexity and accuracy...
