Embodiment Construction

[0057] The core idea of ​​the present invention is to set up a shared memory in the chip, provide a data sending and receiving buffer area, especially provide a channel for data sharing, and different processing cores in the chip write data to preset address units in the shared memory, and Notify the other party to read, so as to send, receive and interact with data in the shared memory, and realize communication between different processing cores. The data read and write operations are fast and the real-time performance is strong.

[0058] Furthermore, through the shared memory and the Bridge module of the shared memory, data channels for different cores in the chip to directly cross access the peripherals of the other party are established.

[0059] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodimen...

Abstract

A chip used for realizing communication between multi-kernel in chip is prepared as setting a sharing storage in chip, providing data transceiving buffer region and data staring channel, carrying out data transceiving and interacting in said sharing storage to realize communication mechanism of data-sharing and data-interacting as well as interruption-interacting by using ARM kernel and DSP kernel to write data in address unit preset by ARM kernel / DSP kernel through said sharing storage and informing the opposite party to fetch data.

Description

technical field [0001] The invention relates to wireless mobile terminal communication technology, in particular to a chip and a communication method capable of realizing communication between multiple cores in the chip, especially between ARM cores and DSP cores. Background technique [0002] With the rapid development of large-scale integrated circuit technology and mobile communication technology, people's requirements for real-time signal processing of intelligent instruments, test systems, communication systems and control systems are also increasing. The requirements are becoming more and more urgent, and the chip system (SOC, System On Chip) technology developed based on advanced reduced instruction computer (ARM, Advanced RISC Machines) technology and digital signal processor (DSP, Digital Signal Processor) technology can better meet People's requirements for real-time signal processing meet the real-time and high-efficiency communication requirements for data in ind...
