Problems solved by technology

[0004] In the prior art, the interaction response time between chips depends on the interface communication rate and command parsing time. The interface UART is usually dozens to hundreds of Kbps, and SPI and USB are usually several Mbps. The communication between some chips cannot Respond quickly to orders

Abstract

The invention relates to an integrated circuit and control method for fast communication between chips. The integrated circuit includes at least two chips. The chips include signal definition modules,interrupt signal generation modules, communication modules and processing modules; the signal definition modules are used for defining interrupt signals which indicate working status of the chips; the interrupt signal generation modules are used for generating the interrupt signals corresponding to the preset working status when the chips are in the preset working status; the communication modules are used for sending the interrupt signals to the chips communicating with the communication modules, and receiving the interrupt signals sent by the chips communicating with the communication modules; the processing modules are used for determining the working status of the chips communicating with the processing modules according to the received interrupt signals. By means of the integrated circuit and control method for the fast communication between the chips, the problem of synchronous control over communication interfaces between the chips is solved, command interaction between the chips is reduced, communication time is saved, efficiency is improved, and software processing procedures are simplified.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an integrated circuit and a control method for rapid communication between chips. Background technique [0002] In the prior art, chip-to-chip communication is generally carried out through specific interfaces and defined commands. After one party initiates a command, the other party receives the command, analyzes the command and then performs a reply or related operations. Usually, the standard HCI (Host Controller Interface) interface is used to standardize communication. The interface adopts such as Universal Asynchronous Serial Receiver / Transmitter Interface UART (Universal Asynchronous Receiver / Transmitter), Universal Serial Bus USB (Universal Serial Bus), Serial Peripheral Interface SPI (Serial Peripheral Interface) interface. Both use the above interface to perform operations such as status control, query, and data transmission through the standard commands de...
