Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. scope.

[0042] As mentioned above, at present, the embedded real-time operating system can only use the serial calculation method to calculate the scattered echoes of multiple targets one by one. When the number of targets to be calculated is large, the serial calculation method takes a long time to calculate. ,low efficiency. If the computing efficiency needs...

Abstract

The invention provides a multi-target scattering echo parallel computing method and device, equipment and a storage medium, the method is applied to a VxWorks system carried on a hardware platform, and the method comprises the following steps: determining the number of CPU cores and the number of to-be-processed targets in the hardware platform; creating more than two computing tasks corresponding to the CPU cores according to the number of the CPU cores in the hardware platform; determining a target having affinity with each CPU core according to the number of the CPU cores in the hardware platform and the number of the targets; and on each CPU core with the target with the affinity, calling a corresponding calculation task to calculate the target with the affinity with the CPU core. According to the scheme, different CPU cores can call respective corresponding calculation tasks to complete the calculation process in parallel, and compared with serial calculation, the calculation efficiency of multi-target scattering echo calculation on an embedded real-time operating system is greatly improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of signal processing, and in particular to a multi-target scattered echo parallel computing method, device, equipment and storage medium. Background technique [0002] In air-space confrontation scenarios, it is often necessary to calculate the scattered echoes of multiple targets. In order to ensure the real-time calculation, the embedded real-time operating system is usually used to calculate the scattered echoes of multiple targets. At present, the embedded real-time operating system adopts a serial calculation method to calculate the scattered echoes of multiple targets one by one. The serial calculation method not only takes a long time to calculate, but also has low efficiency. Contents of the invention [0003] Based on the problems of long calculation time and low efficiency of the serial calculation method, the embodiment of the present invention provides a multi-target sca...
