Abstract

The invention relates to a transaction scheduling method. The method comprises the following steps of enabling a scheduling unit of an operating system to process transactions, divide the processed transactions into different transaction types, establish a data structure for the transactions needing to be processed, and connect the data structure into a queue, wherein the processing process comprises the following steps: step 1, popping up the transactions; step 2, dividing the transactions into a ready transaction queue and a plurality of synchronous transaction queues by the scheduling unit;step 3, selecting a transaction from the queue by the scheduling unit according to a rule, and distributing a thread for the transaction; and step 4,enabling the scheduling unit to distribute the transactions to the CPU for processing. The method has the beneficial effects that human errors can be effectively avoided, meanwhile, software bugs are reduced, and the software development efficiency is greatly improved.

Description

technical field [0001] The invention relates to a transaction scheduling method of a computer operating system, in particular to a transaction scheduling method of an embedded computer operating system. Background technique [0002] When the current computer runs under the control of the operating system, it uses threads as the execution unit. The processes of running, stopping, switching, blocking, and sleeping of threads directly reflect the running process of the CPU. The traditional operating system takes this as a starting point and designs a scheduling system. Threads form several queues in memory. The operating system kernel allocates CPU time to each thread according to a certain algorithm. It also provides a series of API functions. Programmers can create threads by calling these API functions, and control the running, stopping, sleeping, blocking and other processes of threads. This process is highly related to the running process of the computer, and it is compl...
