Title:
PROCESSING CONTROLLER
Document Type and Number:
Japanese Patent JP3008890
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain improvement in efficiency in processing to input data by performing preferential control processing based on the arithmetic result concerning the execution time of selected processing.
SOLUTION: When plural processing start requests compete, a preferential control part 4 controls the operation of processing execution part 7 by identifying processing for every input data through a processing identification part 2, storing the initial value of execution time for every processing and a value showing the important degree of processing through a constant storage part 5, calculating the execution time based on the constant number stored in the constant storage part 5 through an arithmetic part 6 and determining the priority of processing from the arithmetic result at the arithmetic part 6 by the preferential control part 4 and an operation of a process executing part 7 is controlled. Therefore, when processings (a) and (b) for long and short execution time are generated and the processing (a) is first executed, for example, the processing (b) is waited just for the execution time for processing (a) but since the priority is found by calculating the execution time for the respective processings (a) and (b) before executing the processing (a), the processing (b) for shorter execution time is first executed so that the latency can be shortened.
