Embodiment Construction

[0041] figure 1 It is a hardware structural diagram of the synchronization processing device of the present invention. The hardware part of the synchronization processing device is mainly composed of a synchronization flag group, a synchronization processing management control unit, an input / output buffer unit and the like. The connection relationship among the components of the synchronous processing device is shown in the figure. The input and output buffer registers are used to store input or output program drivers. The synchronization flag group includes N synchronization flags, and each synchronization flag has n bits. The synchronous processing management control part is used to manage and control the operation of the entire synchronous processing device, such as the reception of the management program driver, the execution of the operations specified by each synchronization command, the maintenance of the synchronization flag, the transmission of the control program d...

Said method includes: synchronous processing method, program driver drive method of L structure CPU and program drive method of L structure CPU after the synchronous processing device is added, and said equipment includes N timing marks, input buffer storage register, output buffer storage register, busy/idle marks of input/output buffer storage registers and operation/control component.

Description

technical field [0001] The invention relates to the technical field of computer synchronization, in particular to a synchronization processing method and a device thereof. Background technique [0002] The synchronous processing function is a very important function of the computer, because the purpose of multi-program coordination can only be realized with the help of the synchronous function. In modern large-scale applications, synchronization will become one of the important bottlenecks of performance, resulting in a large delay overhead. [0003] When a certain program needs to wait for a certain synchronization flag, the traditional synchronization processing method mainly handles it through the interrupt method. Because this method needs to change lanes many times, and save and restore the scene, the cost is high and the efficiency is low. A new, alternative method of interrupt processing, that is, a method and device for slow program execution, has been invented. U...
