MIPI (Mobile Industry Processor Interface), MIPI control method, MIPI control device and medium

Abstract

The invention relates to the technical field of integrated circuits, and provides an MIPI (Mobile Industry Processor Interface) aiming at the problem that MCU (Microprogrammed Control Unit) resources are occupied due to the fact that MIPI signals are analyzed and simulated in a software mode through an MCU (Microprogrammed Control Unit) at present, which comprises an MIPI bus, a plurality of buffers, a state machine, a transmitting data processing module, a receiving data processing module and an SRAM (Static Random Access Memory), when external equipment inputs data, the received data processing module analyzes the data to obtain serial data and state codes; the state machine performs state jump according to the state code, and the receiving data processing module converts the serial data into byte data according to the current state of the state machine; and when the MCU outputs the data, the transmitting data processing module acquires the data written by the MCU from the SRAM and outputs the data through the MIPI bus. According to the application, the conversion between the MIPI signal and the byte data is realized through the hardware device, and the MCU does not need to simulate and analyze the MIPI signal in a software form, so that the running resources of the MCU are saved, and the efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, and in particular, to a MIPI interface, and a control method, device and medium thereof. Background technique [0002] With the rapid development of information technology and mobile portable devices, people have higher and higher requirements for mobile devices. On the premise of satisfying high-performance display effects, the power consumption of mobile devices should also be reduced as much as possible. At present, the mainstream video interface in the mobile field uses the Mobile Industry Processor Interface (MIPI) interface. MIPI defines the interface specification for high-speed data transmission and low-power transmission, and MIPI D-PHY is the physical layer standard of the MIPI interface. . In the practical application of MIPI, there is an application that only needs to support MIPI low-power mode data. This application requires MIPI to work in low-speed mode. Th...
