The invention belongs to the technical field of embedded software testing, and provides a VSIPL vector library function testing method and device.The method comprises the steps that operator functions to be tested are classified and abstracted into uniform function pointers, test cases are constructed based on the function pointers, and a corresponding relation table of the test cases and VSIPL data object specifications is established; automatically generating a matched VSIPL data object according to the relation table, calling the operator function to be tested and the reference operator function corresponding to the operator function to perform calculation on the same data, outputting a test result based on a calculation result and consumed time, and releasing resources. According to the method, on-demand self-adaptive generation of test data and unified scheduling of operator functions are realized through a cooperation mechanism of a function pointer and a relation table, the automation degree, coverage integrity and cross-platform verification efficiency of VSIPL vector library test are remarkably improved, batch performance and precision evaluation is supported, and the method is suitable for popularization and application. And the correctness and the acceleration effect of the optimized version function are effectively ensured.

The application provides an operator calculation method, device, equipment and system in the field of artificial intelligence. The method comprises the following steps: acquiring parameter data of a first data shape of an AI network, the first data shape being a data length in each dimension supported by the AI network for processing, the parameter data comprising combination information of at least two calculation units, the data supported by each calculation unit for processing being data with a second data shape, and the data length of each calculation unit in any dimension after combination according to the combination information being greater than or equal to the data length of the first data shape in the same dimension; and calling the at least two calculation units to perform calculation on first target data with the first data shape. Therefore, the application supports the change of the data shape in any range by combining the at least two calculation units, realizes the AI dynamic shape operator function, and improves the AI network starting speed.

The present application relates to a kind of computing operator fusion method and device, readable medium, program product and electronic equipment.The method includes: the data dependency between multiple operators in received computing stream and operator is parsed;Directed acyclic graph is constructed;Multiple candidate fusion strategies are generated based on the topological structure of directed acyclic graph;According to each candidate fusion strategy, reconstruct computing stream, and same fusion mark is assigned to the node divided in same fusion group;The reconstructed computing stream is compiled, and intermediate representation code is generated in the process of compiling, and the code logic of the node with same fusion mark in intermediate representation code is merged to generate a fusion operator function;The performance of each candidate fusion strategy containing fusion operator function is evaluated, and target fusion strategy is screened out from multiple candidate fusion strategies.The technical scheme of the present application realizes the full-process automation of operator fusion, breaks through the limit of artificial experience, and ensures that the global performance is better across hardware platform.
