Problems solved by technology

make the queuing circuit less reliable
And, the polling queuing counter starts the polling queuing process when the currently selected branch application signal is invalid, and when the application signals of each branch are all invalid, that is, when each branch does not have data that needs to be processed, polling The queuing counter will continue to poll the queuing process, increasing the design power consumption of the queuing circuit

Embodiment Construction

[0055] In the present invention, when the queuing circuit is in a dead state, by actively clearing the valid state of the currently selected branch application signal, the queuing circuit can continue to realize the polling and queuing function of each branch application signal. Therefore, the core of the present invention Yes: Obtain the currently selected branch application signal according to the current branch information, and time its valid state, and when it is determined that the timing value of the valid state exceeds the predetermined time threshold, clear the valid status of the currently selected branch application signal According to the invalid state of the currently selected branch application signal, polling and queuing are performed for each branch application signal, and the current branch information is updated according to the polling and queuing result.

[0056] The technical solution provided by the present invention will be further described below based on...

Abstract

The method includes: obtains the applying signals in currently selected branch, and times its valid state; when the timing of the valid state is over the preset threshold, deletes the valid state of the applying signal in the currently selected branch; makes polling queue for the applying signals in each branch in term of invalid state of applying signals in the currently selected branch; in termof result of polling queue, renews the message of the branch. The invention can find hanging up state in queue circuit, and makes the queue circuit recovered from hanging up state to take normal polling queue process. The invention can stop the polling queue, when the applying signals in all branches are in invalid state, namely there is no signal to be processed.

Description

technical field [0001] The invention relates to the technical field of queuing circuits, in particular to an application-driven polling queuing method and device. Background technique [0002] The queuing circuit is a commonly used design in digital circuits, and the queuing principle it adopts is: the principle of equal probability for each branch. [0003] At present, the general model of the queuing circuit is attached figure 1 Shown: [0004] exist figure 1 Among them, the queuing circuit consists of three parts: the front-end system, the queuing module, and the back-end system. [0005] The front-end system sends N channels of application signals Request_0 to Request_N, and N channels of data Data_0 to Data_N to the queuing module. [0006] The queuing module polls and queues Request_0 to Request_N, determines the currently selected branch application signal according to the queuing result, and transmits the data Data_output and interrupt signal Request_output corre...
