Abstract

The invention relates to a navigation resolving apparatus based on a heterogeneous multinucleated architecture. The apparatus comprises a heterogeneous multinucleated processing core, a sensor input interface connected with the heterogeneous multinucleated processing core through an input interface control chip and a data output interface connected with the heterogeneous multinucleated processing core through an output interface control chip, wherein the heterogeneous multinucleated processing core comprises a field programmable gate array (FPGA), an ARM dual-core processor and a DSP dual-core processor; the FPGA is connected with a nonvolatile memory and a synchronous static random access memory DDR3; and the DSP is connected with the DDR3. According to the invention, the requirement for real-time performance of high-frequency navigation information output and subsequent processing operation under astronomical, inertia and satellite and deep integration conditions can be effectively satisfied, the problems of high-speed data exchange mechanism and an information synchronization mechanism between basic processing units of a multinucleated system are solved, the hardware structure can be expanded and can be cut, the apparatus can be adapted to multiple different navigation demands and processing methods, and the real-time performance, the flexibility and the reliability are quite good.

Description

technical field [0001] The invention belongs to the field where image processing technology intersects with navigation technology, and relates to a navigation solution device based on a heterogeneous multi-core architecture, which realizes the output signal of high-frequency navigation attitude information under the conditions of sky, inertia, satellite and their deep combination Processing device. [0002] technical background [0003] In the modern air-ground integrated warfare system, any single navigation system is often difficult to meet the requirements of various military navigation. It is necessary to combine two or more navigation systems to take advantage of the advantages of each system and make up for the shortcomings, so that the new The advanced navigation system has excellent performance that a single navigation system does not have. [0004] At present, the design of the navigation system in China is mainly based on the structure of FPGA+DSP. The data acquisi...
