The invention discloses a novel script development method based on a JVM (Java Virtual Machine), which comprises the following steps of: S1, setting a script permission list and a script forbidding list in a system configuration file, setting an initial variable and configuration information of a script, and monitoring the change of the configuration file by using an observer mode; s2, collecting external input data by utilizing a response type programming library, performing conversion processing by taking the external input data as an event, and adding the external input data into a script running context; s3, analyzing script contents into marks and nodes, and constructing an abstract syntax tree; s4, checking whether the variables of the abstract syntax tree accord with the permission and prohibition lists in the configuration file or not; s5, traversing the abstract syntax tree, and executing node logic of the abstract syntax tree; and S6, collecting execution results of all nodes, and returning the results to a caller. According to the method, configuration changes are monitored through an observer mode, syntax analysis and security check are carried out in combination with an abstract syntax tree, and the functions of script online development and real-time adjustment are achieved.

The invention belongs to the technical field of FPGA (Field Programmable Gate Array) peripheral configuration, and discloses a CPLD (Complex Programmable Logic Device)-based SelectMAP configuration mode implementation method and system. The method comprises the following steps: electrifying equipment; clearing the configuration register; a sampling configuration mode pin; a mode is configured for the SelectMAP synchronously; checking the ID of the equipment; loading the configuration data; performing CRC (cyclic redundancy check); starting a sequence; and the SalveSelectMAP configuration control module at the CPLD end is used for pre-storing bit stream configuration data into FIFO (First In First Out) when the configuration data is valid, and then configuring the bit stream configuration data into an FPGA-K7 through a SelectMAP interface by matching with a configuration clock generated by the SalveSelectMAP configuration control module. According to the invention, a high-performance configuration data transmission channel is realized. The configuration scheme has the characteristics of simplicity in development, low configuration cost, high speed and flexibility in use, and has very high practicability.

The invention relates to a reconfigurable computing architecture-oriented file compiling method and a software development tool chain, and the method comprises the following steps of: performing language translation processing on an initial compiling program file by adopting a language compiler in a pre-designed software development tool chain to obtain an intermediate representation file; and compiling the intermediate representation file by adopting a reconfigurable computing architecture compiler in the software development tool chain to obtain an executable file for execution of the reconfigurable computing architecture. According to the method, the initial compiling program file is efficiently compiled into the executable file for the reconfigurable computing architecture, so that the execution efficiency of codes is improved, the advantages of the reconfigurable computing architecture are fully utilized, the development and operation environment is more flexible, and the software development requirements are met.

The application discloses an instant information publishing method, system and device supporting interactive transaction and a storage medium. According to the needs of actual power grid balanced operation in a control area or after the interactive transaction application of market subjects in the control area to a power transaction center is audited and passed, the power transaction center broadcasts interactive transaction information to all market subjects in the control area through a power transaction platform. In the transaction process, the market subjects can dynamically adjust the declared transaction information at any time. At this time, the power transaction center publishes transaction adjustment information to other market subjects in the whole range which have participated in the interactive transaction through the power transaction platform. After the transaction result is published or after the market subjects propose transaction termination application within the specified transaction time and obtain the approval of the power transaction center, the interactive transaction is ended. The application can realize instant publishing of interactive transaction information, meet the stability of transaction time and transaction cycle of the interactive transaction and promote the smooth development of the interactive transaction among the market subjects.
