System-on-Chip with on-chip parallel interface

Abstract

The invention relates to a system-on-chip with an on-chip parallel interface. The system-on-chip includes an MCU core and an FPGA module interacting through a system bus, wherein at least one parallel interface is constructed on-chip by utilizing the programmable logic resources of the FPGA module. Each of the parallel interfaces includes more than two parallel channels, and the number of parallel channels and the data width of each parallel channel are dynamically configured through the MCU core. The system on chip adopts the parallel interface provided in the chip for data transmission, which is expected to obtain a higher transmission rate, which improves the application flexibility of the system on chip, and the number of parallel channels of the parallel interface and the data of each parallel channel The width can be dynamically configured according to the needs, which is convenient for users to use and meet diverse data transmission needs.

Description

technical field [0001] The invention relates to the field of FPGA development, in particular to a system-on-chip with an in-chip parallel interface. Background technique [0002] The functions and performances 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, the industry has proposed a system-on-chip (SoC) architecture based on FPGA and MCU (Micro-controller Unit, microcontroller) that integrates the advantages of FPGA and CPU. Devices, etc. are connected to the FPGA core, and external devices can be freely expanded according to different application scenarios. It has good scalability and meets the needs of different application fields. It has become a technology hotspot. [0003] The communication interface betwee...

Problems solved by technology

[0003] The communication interface between the MCU and external devices includes two types: serial interface and parallel interface. The serial interface adopts serial communication mode, and the communication line is simple, but the data can only be transmitted bit by bit, and the transmission speed is slow.
