Problems solved by technology

[0005] (1) It needs to be operated under the premise that the laser inertial group has not completed the assembly and sealing. After the assembly is completed, the inertial group must be disassembled;
[0006] (2) The construction of the simulation environment requires special equipment and professional DSP designers, and the operation is cumbersome;
[0007] (3) It is necessary to manually compare files offline, which is inefficient
[0009] (1) For different sectors, repeated programming operations are required, and the efficiency is low;
[0010] (2) Due to human negligence, it is easy to cause missed burning and missed judgment of the sector, and the reliability is poor;
[0011] (3) The method of first verifying and then programming cannot avoid errors in the programming process, and the reliability is poor

Abstract

The invention relates to a DSP (Digital Signal Processor) multi-core data programming method based on a 1553B bus, in particular to a method for performing multi-core data programming operation on a laser inertia measurement unit with a DSP programming module. According to the invention, communication and instruction control with the programming module are realized, and programming upgrading of computer board 03 nuclear inertia measurement unit software, element coefficients, temperature compensation parameters and the like is realized by selecting corresponding BIN files.

Description

technical field [0001] The invention relates to a DSP multi-core data programming method based on a 1553B bus, in particular for performing multi-core data programming operations on a laser inertial group equipped with a DSP programming module. Background technique [0002] After the development of inertial group software enters the stage of operation and maintenance, how to realize the rapid, simple and reliable upgrade of inertial group software is a key issue in the stage of operation and maintenance of inertial group software. In addition to the maintenance and upgrade of the software, the metadata stored in the inertial group also needs to be updated during the maintenance phase. The accuracy of the laser inertial group is affected by its own various error factors, and it needs to be calibrated regularly, and the calibrated zero offset, scale factors, and installation Coefficients such as errors are burned into the inertial computer board. The IMU computer board DSP ne...
