Abstract

The invention relates to a system-on-chip supporting USB and GPIO conversion and a communication method. The system-on-chip is integrated with an MCU (Microprogrammed Control Unit) module, an FPGA (Field Programmable Gate Array) module, a bus system, a USB (Universal Serial Bus) interface and a GPIO (General Purpose Input/Output) interface, wherein the USB interface and the GPIO interface are configured by utilizing hardware logic resources of the FPGA module, and the system-on-chip is also provided with a bridging system for connecting the USB interface and the GPIO interface. The system-on-chip gives consideration to the functions and advantages of an MCU and an FPGA, facilitates the meeting of diversified system functional requirements, avoids the design complexity caused by the use ofa USB-to-GPIO dedicated control chip through the setting of the bridging system, enables the design of a user to be more flexible, and is lower in cost. The method adopts the system-on-chip to carry out communication.

Description

technical field [0001] The invention relates to the field of FPGA application, in particular to a system-level chip supporting USB and GPIO conversion and a communication method. Background technique [0002] The function and performance of traditional FPGA (Field Programmable Gate Array, field programmable gate array) and CPU (central processing unit) discrete devices are increasingly difficult to meet the increasingly large and diverse data processing requirements. In order to meet the requirements of performance, scalability and integration Requirements, the industry has proposed a system-on-a-chip (SoC, also called system-on-chip) architecture based on FPGA and MCU (Micro-controller Unit, microcontroller) that integrates the advantages of FPGA and CPU. MCU (microcontroller) usually focuses on the number of I / O interfaces and the size of programmable memory, which is suitable for a large number of input and output (I / O) operations, but its processing power and I / O resourc...
