Abstract

The invention provides a data interaction system with a plurality of external interfaces, which comprises a plurality of external main control end modules, a plurality of external interface modules and interface conversion modules, wherein the external main control end modules correspond to the external interface module, command words and data are predefined according to an interaction protocol with an internal bus and are transmitted through the external interface modules, the external interface modules are respectively used for transmitting the corresponding command words and the data to the interface conversion modules, and the interface conversion modules analyze and convert the command words and the data according to the data interaction protocol for executing the data interaction with the internal bus. The invention can improve the consistency and the importance of the interactive design of the external interfaces and the internal data.

Description

technical field [0001] The invention relates to peripheral interface communication technology, in particular to a data interaction system and method with multiple peripheral interfaces. Background technique [0002] System on Chip (SOC) chip refers to the integration of all functional systems required for microelectronic application products on a single chip. It is an integrated chip that realizes the maximum tolerance of the product system. With the development of SOC chip technology, a single chip generally requires Quite a few peripheral interfaces, such as Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I2C), Secure Digital I / O (SDIO), Universal Asynchronous Receiver / Transmitter (UART), etc. And external chips often need to access the internal module registers and memory through the corresponding peripheral interfaces. [0003] At present, data interaction between external devices and internal registers is generally adopted figure 1 The way shown: that is,...
