The invention relates to a distributed embedded software testing system based on resource sharing. The distributed embedded software testing system comprises a plurality of nodes, wherein each node isinternally provided with a simulation module for carrying out simulation verification on the embedded software, and a resource management module; access of the nodes to input behaviors and output behaviors of the system is achieved through mapping of input and output provided by the resource management module so as to realize that a network capable of resource sharing can be established by the plurality of nodes; and the resource management module is used for scheduling remote resources when the remote resources are used by applications in the nodes, and the remote resources comprise a remoteshared memory and remote program calling. The distributed embedded software test system based on resource sharing provided by the invention not only can meet the scale expansion of an embedded software operation platform, but also can realize the sharing of internal resources of the software operation platform under a distributed architecture.
Description
technical field [0001] The application belongs to the technical field of digital simulation, in particular to a distributed embedded software testing system based on resource sharing. Background technique [0002] With the development of equipment software systems, more and more hardware functions are softwareized, and the development of equipment software is developing towards the trend of high comprehensiveness, high integration, and integration. Software gradually occupies the leading position in equipment functions, and 80% of airborne Functions are implemented by software, so software defects and errors have become one of the most important factors affecting system security. [0003] In the current aerospace equipment software, embedded software occupies a dominant position. Compared with general-purpose computer software, the testing of embedded software is oriented to specific applications, supported by real-time operating systems, and the operating chips and platform...
