Example 1
As shown in fig. 1, a method for issuing and executing instructions in a multi-association device is to implement control of a device in the whole instruction stream by using one instruction in a multi-association device context, and implement parallel execution of multiple execution logics without mutual interference in execution dependency logics of previous and subsequent results between devices; the specific process is as follows:
firstly, a complete instruction SPL statement is segmented, and sub-instructions for each device are extracted.
And secondly, converting the extracted sub-instructions for each device into two-dimensional tables, wherein the two tables respectively record the former device and the latter device of each device and the execution result of the instructions required to be executed by each device.
Thirdly, when the sub-instruction of the whole multi-device is issued and executed, when the device instruction in a part of sub-sentences is executed, judging whether devices which depend on the front and back exist or not at first, if so, judging the instruction execution condition of the devices which depend on the front and back exist, and executing the sub-sentence instruction of the next node only when the execution state of the front node in the sub-sentence is successful, wherein the front node is a precondition for judging whether the sub-sentence instruction is executed or not, and the back node is a precondition for ensuring the continuity of the whole sub-instruction; the success of the execution of the sub-instruction must be determined by the following criteria that all pre-dependent sub-instructions of the sub-instruction are completed and executed only if the sub-instruction is successfully executed, and the head sub-instruction does not have a dependent sub-instruction (the head sub-instruction must be directly executed).
