System-level chip and communication method supporting usb and gpio conversion

Abstract

The invention relates to a system-level chip supporting USB and GPIO conversion and a communication method. Described system level chip is integrated with MCU module, FPGA module, bus system, USB interface and GPIO interface, and described USB interface and GPIO interface all utilize the hardware logic resource configuration of FPGA module, and described system level chip also has connection USB interface and The bridging system of the GPIO interface is used to realize the data format conversion between the USB interface and the GPIO interface under the control of the MCU module. The system-on-a-chip takes into account the functions and advantages of MCU and FPGA, which helps to meet diverse system functional requirements, and, by setting the bridging system, avoids the design complexity of using a USB-to-GPIO dedicated control chip, Make user design more flexible, and the cost is lower. The method uses the system-on-a-chip to perform 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...

Problems solved by technology

[0003] For the system-on-chip based on FPGA and MCU design, in order to connect with different kinds of external devices, the system-on-chip needs to be configured with different types of interfaces, but if it is necessary to establish connections between external devices with different interfaces, the current design It needs to be configured with a dedicated transfer interface controller (or control chip), which is costly and limits the flexibility of user design
