Description

DNOC register configuration method and device and electronic equipment Technical Field The present application relates to the field of processor systems, and in particular, to a method and an apparatus for configuring a register of a DNOC, and an electronic device. Background DNOC (Data Network On Chip, network on chip) is a core data transmission architecture in a multiprocessor system, and is responsible for establishing a data migration channel between target processors, and the register configuration precision and efficiency of the DNOC directly affect the overall performance of the system. To improve the flexibility and performance of multiprocessor system deployment, DNOC modules have added a number of configurable registers, but this also presents significant challenges for subsequent software adaptation operations, embodied in three ways: First, register configuration is extremely complex and understanding costs are extremely high. The number of the newly added registers of the DNOC is large, the functions of the registers are complex, the configuration rules are complex, a software team needs to deeply read a programming guide to correctly use the registers, the software team is required to directly write the configuration code of each register in a driver program manually, configuration errors are easily caused by understanding deviation or negligence, and the errors are often difficult to find in a coding stage. Secondly, the debugging efficiency is low, and the resource waste is serious. Firmware/drive failures due to register understanding bias or manual coding errors occur frequently during the post-chip emulation and emulator testing phases. These problems require hardware and software team collaborative debugging to locate, consume significant human resources and severely extend project cycles. Third, the risk of development increases significantly. The software team needs to invest a lot of time to comb the register function, write and verify the register configuration codes, and the hardware team needs to continuously intervene in debugging the test failure caused by understanding the error. And the manually written configuration codes lack structural organization, and codes of different configuration scenes are mixed, so that multiplexing and maintenance are difficult. This introduces a great uncertainty to the development of drivers and firmware, increasing project delays and product stability risks. The prior art lacks a systematic DNOC register configuration management mechanism, and the configuration information is decentralized and difficult to multiplex. In view of the large-scale, multi-scenario register configuration requirement, a solution is needed that can reduce configuration complexity, improve accuracy, and reduce debug costs. Disclosure of Invention The embodiment of the application provides a register configuration method, a device and electronic equipment of DNOC, which realize configuration framework unification and flow automation through a standardized configuration template, obviously reduce configuration complexity and maintenance cost and improve debugging efficiency. In a first aspect, an embodiment of the present application provides a register configuration method of a DNOC for configuring and managing a data interconnection path between a plurality of target processors in a multiprocessor system, the method comprising the steps of: When the DNOC registers are required to be configured, reading a pre-stored register configuration file from a preset storage medium and extracting configuration information of the registers to be configured, wherein the register configuration file is obtained by filling the configuration information of the registers to be configured on the basis of a standardized configuration template which is generated according to DNOC register configuration rules; generating a configuration instruction which can be identified by the DNOC based on the extracted configuration information of the register to be configured; And sending the configuration instruction to the DNOC to complete the register configuration of the DNOC. Optionally, the standardized configuration template is taken from a predefined configuration template database; the configuration template database provides a unique corresponding standardized configuration template for each configuration scene in the multiprocessor system; Each standardized configuration template at least comprises a configuration scene identifier, a register address and a configuration value field of a register related to a corresponding configuration scene in the DNOC, wherein the configuration value field is used for providing a standardized placeholder for filling corresponding configuration value information when generating a register configuration file; The configuration scene refers to a specific hardware environment which is defined by a system topology structure of the multiprocessor system and a targ
