Abstract

The invention discloses a method for reading a dynamic memory mapping file in ground test device embedded software, and relates to the technical field of data processing. According to the method, a ready thread preprocessing unit obtains information collected by a file occupation space obtaining module, a CPU collection module and a current thread time slice obtaining module, and performs memory mapping operation according to a memory mapping size of a target file; a data exchange module is used for data exchange operation; a thread time slice is correspondingly adjusted; and cyclic mapping reading of data is performed according to a calculated value. Through dynamic mapping of a big data file, a particle size value of mapping subsections is dynamically changed along with factors such as afile size, an embedded software state and the like, and the size of an execution time slice is dynamically adjusted according to reading time of each section of mapping, so that the file reading andthread execution efficiency is effectively improved and the resource overhead is reduced.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a dynamic memory mapping file reading method applied in embedded software of ground test equipment. Background technique [0002] Without loss of generality, taking the aerospace measurement and control system and the air-ground communication system as examples, the ground test equipment is responsible for the all-round and multi-scenario ground test verification of the transponder, and the human-computer interaction function is an important function of the embedded software of the ground test equipment . The embedded software realizes the human-computer interaction function and is the main control software of the ground test equipment. In the embedded software of the ground test equipment, the file reading method of the software is an important factor affecting the performance of the embedded software. The average response time of existing methods for readi...
