CHI protocol anti-blocking interconnection method, system and device and storage medium

Abstract

The invention provides a CHI protocol anti-blocking interconnection method. The method comprises the following steps: establishing a request counter at a request end of a CHI protocol transmission link; responding to a data transmission request sent by a request end, adding 1 to the value of a request counter, and judging whether the value of the request counter is equal to a preset value or not; and forbidding the request end to send the data transmission request in response to the fact that the value of the counter is equal to the preset value. Through the method, the request counter and the buffer are respectively established on the hardware circuits of the request end and the response end of the transmission link of the CHI protocol, and the number of requests in the transmission link is controlled through the buffer and the counter. Under the condition that the scale of a chip circuit is kept unchanged, the rate of cache congestion paths of all levels of components is reduced, and when the circuit continuously and effectively works for a long time, the system access efficiency is greatly improved. According to the invention, the circuit design resources are optimized, the circuit structure is simplified, the complexity of the chip back-end design is reduced, and the design complexity of the whole chip system is reduced.

Problems solved by technology

For large-scale high-speed protocol processors, the amount of data processed per unit time is quite large, and there is no necessary correlation. Using conventional methods will cause the cache of each component to reach the upper limit of processing capacity, resulting in a very high rate of channel congestion. Traditional CHI-based The method of protocol processing can no longer meet the requirements, which will have a relatively large negative impact on the overall performance of the system
