Abstract

The invention provides a method for high-speed data transmission between multiple cores. The method comprises the following steps of building a section of shared memory with a fixed size between inner cores, designing the shared memory into a form of an annular buffering region, initializing a CPPI (communications port programming interface), then judging whether the CPPI is provided with an unoccupied buffering region if a sender inner core intends to send data, taking out a CPPE (communications port programming element) pointer from the CPPI through a receiver inner core if the CPPI is provided with the unoccupied buffering region, and directly processing the data to implement data transmission. According to the method, data copying can be reduced, and the problem of data read-write conflicts of the shared memory can be solved; the transmission efficiency and the transmission stability of the data are improved under a condition of high data rate.

Description

Technical field

[0001] The present invention relates to the field of wireless communication, in particular to a method for high-speed data transmission between multiple cores. Background technique

[0002] In the design of VOIP terminal equipment, it is often encountered that a large amount of network audio data needs to be transmitted in real time. This kind of data transmission requirements are generally relatively high, such as stability, reliability, and low latency. Especially when the CPU frequency of the communication terminal equipment is not high, these audio data require high-speed and stable transmission and storage between multiple cores, which is undoubtedly a difficult problem. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a method for high-speed data transmission between multiple cores, which can improve the system and rate performance.

[0004] In order to achieve the above objective, the present invention prov...
