System shared resource allocation method

Abstract

Among several drive programs using the same system resource, sorting control mechanism is established so as to avoid instability and crash caused by different control mechanisms and excessively complicated program during executing multiple drive program in operate system with multitask application and programming interface. The shared system resource distributing method includes using one independent program for controlling the common resource, and the independent program receives the request information from several drive programs, sorts and generates execution program list, affords the first drive program the control right to execute the first drive program, renews the execution program, retracts the control right from the executed drive program, and further executes other drive program.

Description

technical field [0001] The present invention is a method for allocating system shared resources, especially a method for allocating system shared resources in an operating system capable of multitasking execution application programming interface (application and programming interface, API). Background technique [0002] With the advancement of science and technology, while the pace of human life is accelerating day by day, many electronic devices have emerged to assist humans in handling daily affairs. Powerful data calculation functions or larger storage space than traditional devices can be said to be the advantages of such devices. Features, such as the personal digital assistant (PDA) is a high-tech product in the current situation. It caters to the consumers' demands for high mobility and powerful storage functions. Through the built-in operating system provided by various system manufacturers, it attempts to process the computer's executable transactions. The mechanis...

[0004] Later, the operating environment simulated the operation of a personal computer, which is convenient for users to be familiar with after getting used to the computer operation mode; it can realize the effective utilization of the software execution time by synchronously executing the application program interface through multi-tasks, but in this system Among them, for the scheduling and allocation of system resources shared by application programming interfaces, the current operating system only provides control tools, and there is no suggestion, specific, and unified method, so that software engineering abnormalities use different controls according to individual preferences. The management method, even if it is not used, the system often causes the execution sequence to be disordered due to the simultaneous execution of multiple application program interfaces. The phenomenon of conflict will cause system instability and slow down the execution process of the entire system. Therefore, it is a great development to develop a unified mechanism for effectively scheduling and controlling multiple synchronously executed APIs. The link that must be performed by the operating system of the task execution application programming interface
