Abstract

The embodiment of the invention discloses a GNSS data exchange method and system based on an isomorphic multi-core multi-operation system, which are used for improving the data transmission performance between a built-in GNSS module and a processor. The GNSS data exchange system comprises an isomorphic multi-core processor and a GNSS module, the GNSS module is integrated in the isomorphic multi-core processor, a first core of the isomorphic multi-core processor runs and supports a first operating system of the GNSS module, and a second core of the isomorphic multi-core processor runs and supports a second operating system of an application program. The method provided by the embodiment of the invention comprises the following steps: writing first GNSS data into a multi-channel circular queue in a first memory space through a first operating system, so that a second operating system reads the first GNSS data from the multi-channel circular queue; and / or, writing second GNSS data into the multi-channel circular queue in the first memory space through the second operating system, so that the first operating system reads the second GNSS data from the multi-channel circular queue.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a GNSS data exchange method and system based on homogeneous multi-core and multi-operating systems. Background technique [0002] The Global Navigation Satellite System (GNSS) module is a module with complex functions and components. With the advancement of hardware technology, some GNSS modules can be integrated into the CPU. In this case, the GNSS module and The CPU often communicates data through memory sharing and other methods. However, the current GNSS module built in the CPU cannot meet the needs of a large amount of data exchange, and the data transmission performance is poor. Contents of the invention [0003] The embodiment of the present application provides a GNSS data exchange method and system based on isomorphic multi-core and multi-operating systems, which is used to achieve the cross-core and cross-operating system data interaction function of th...
