Embodiment 1

[0026] The technical solution of the present invention: a hardware acceleration method suitable for linear fitting of airborne products with more analog quantity acquisition, characterized in that: the method is implemented based on the architecture of FPGA+AD, specifically including analog quantity acquisition, Floating-point data normalization, linear fitting parameter loading, floating-point number multiplication and floating-point number addition are five parts. The five parts in the method are all implemented based on FPGA, and the purpose is to take advantage of the advantages that FPGA logic can perform parallel operations. Complete all analog acquisition results in the airborne product in an automatic cycle, and store the results in registers. The host computer software does not need to participate in the process of analog quantity acquisition and linear fitting operation, it only needs to read the data of the corresponding register when the analog quantity acquisition ...

Abstract

The invention provides a hardware acceleration method, and the method comprises the steps: collecting an analog quantity, wherein the data format of the analog quantity is a binary format; convertingthe data format of the analog quantity into a floating-point number; and according to preset parameters, performing parallel operation on floating-point number multiplication and floating-point numberaddition, and obtaining a calculation result.

Description

technical field [0001] The invention belongs to the technical field of digital circuits, in particular to a hardware acceleration method for linear fitting. Background technique [0002] Analog quantity acquisition is an indispensable data source in the airborne computer system, especially in complex electromechanical systems, there are a lot of analog quantity signal acquisition. Usually in the FPGA, only the data collected by the AD conversion chip is stored in the register or stored in the RAM generated by the FPGA, and the onboard software of the host computer completes the reading of the data and calculates the collection result. Airborne software can only perform serial computing tasks, and the calculation of a large number of analog acquisition results will inevitably occupy a long time for the airborne software task, which will increase the task cycle time of the airborne software and affect the data transmission rate of the upper computer.
