Asynchronous transceiving transmitter peripheral and system based on RISC-V processor

Abstract

The invention discloses an asynchronous transceiving transmitter peripheral equipment based on an RISC-V processor. A data signal output end of the receiving module is connected with a data signal input end of the WB Interface module, and a control signal input end of is connected with a control signal output end of the UART _ Regs module to receive and process data; the data signal receiving endof the output module is connected with the data signal output end of the WB Interface module; a control signal receiving end of the output module is connected with a control signal output end of the UART _ Regs module to realize output of processed data, effective UART module mounting is realized, and the UART module can be directly mounted to n the MIMO interface of the RISC-V, data transmissionis carried out in combination with the RISC-V processor. The invention further discloses an asynchronous transceiving transmission system based on an RISC-V processor, which has the beneficial effectswhich are not repeated herein.

Description

technical field [0001] The present application relates to the technical field of chip design, and in particular, to an asynchronous transceiver peripheral based on a RISC-V processor and an asynchronous transceiver transmission system based on a RISC-V processor. Background technique [0002] UART (Universal Asynchronous Receiver Transmitter Transmitter) is a peripheral device that implements Universal Asynchronous Receiver Transmitter Transmitter. It is mainly used for serial port printing to facilitate the debugging of other modules. It is a common peripheral device. [0003] At present, UART is a peripheral designed based on the x86 and ARM architectures. In order to maintain the backward compatibility of the architecture and the continuous development and maturity of modern processor architecture technology, the architecture of modern x86 and ARM architectures is extremely lengthy, with hundreds of documents. Thousands of pages, complex background operations and design p...
