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

The invention discloses a chip together with the communication method to realize the communication among a plurality of nucleus inside a chip, such as the communication between an ARM nuclear and a DSP nuclear, comprising the ARM nuclear, the DSP nuclear and a shared memory. The chip is internally provided with a shared memory to provide a buffer space for receiving the data, in particular to a shared channel for the data. The ARM nuclear and the DSP nuclear write the data on an address unit presupposed by the ARM nuclear and the DSP nuclear in the shared memory and notify the other party to read the data to do the receiving, sending and interaction of the data in the shared memory, so as to realize the communication mechanism of data sharing, data interaction and interruption and interaction between two nucleus with high reading-writing operation speed, short delayed time and strong real-time performance.

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...
