Method and device for polling arbitration

Abstract

The invention discloses a method and device for polling arbitration. The method comprises the steps that during polling of each channel, it is determined whether the data source in a current channel proposes an arbitration application or not during polling of the current channel; if it is determined that the data source proposes the arbitration application, a data processing state of the current channel is obtained, and it is determined whether the data source is authorized or not according to the data processing state. According to the method for polling arbitration, it is determined whetherthe data source is authorized according to the arbitration application and the processing state, thereby effectively avoiding the data source authorization of the channel having problems in processingstates, improving the scheduling efficiency of the channel, and further improving the efficiency of data processing.

Description

technical field [0001] The present invention relates to the field of data technology, in particular to a polling arbitration method and device. Background technique [0002] In the field of data transmission, the data that needs to be processed often comes from a variety of different data sources. These different data sources are usually in different channels. In the data sources of different channels, external memory is generally used when exchanging data in large quantities. (For example, SRAM (Static Random Access Memory, Static Random Access Memory) caches data. [0003] At present, there are generally two arbitration methods for external memory, one is fixed optimization level arbitration, and the other is polling arbitration. Among them, the rule of fixed optimization level arbitration is to pre-define different priorities of data sources, and high priority responds first. Among them, the rule of polling arbitration is that multiple data sources have the same priorit...

Problems solved by technology

However, in some cases, when accessing the data source in the current channel, because the data source in the current channel submits an arbitration application, the data source in the current channel must be scheduled before accessing other channels. However, if the data source in the current channel There is a problem with the processing status of the source. Such a data source does not require authorization. If the data source with a problematic authorization processing status occupies arbitration resources, it is easy to affect the processing process and cause low processing efficiency.
