Embodiment Construction

[0045] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0046] Such as figure 1 As shown, the single bus transmission method described in the specific embodiment of the present invention includes the following steps:

[0047] Step S100: After receiving the system start signal, the encoding control module generates a control signal and inputs it to the sending encoding module;

[0048] Step S101: Detect whether the control signal generated by the encoding control module 301 is valid; wherein the method for generating the control signal of the encoding control module 301 can be:

[0049] Detect whether the received system start signal is valid;

[0050] If the system start signal is valid, then detect whether the clock data separation module 302 is connected to the circuit; that is, detect whether the clock data separation module 302 is connected to the sendin...

Abstract

The invention discloses a single-bus transmission method, which comprises: receiving a system start signal, an encoding control module generates a control signal and inputs it to the sending encoding module; detects whether the control signal generated by the encoding control module is valid; if valid, generates Coding control signal; otherwise, continue to detect; according to the coding control signal, the sending coding module generates an analog single signal output; according to the decoding principle corresponding to the coding principle, the separated data output signal and output signal are output by the comparison circuit and the decoding circuit clock output signal. The invention also discloses a corresponding single bus transmission system. The present invention simplifies the data bit width of the bus and realizes reliable and simple data transmission control through a simple system and method, through lossless composite encoding and receiving decoding.

Description

technical field [0001] The present invention relates to the technical field of circuits and systems, in particular to a signal transmission method and system. Background technique [0002] The general bus transmission interface of integrated circuits includes bus interface protocols such as IIC / SPI / CAN / UART. The clock and data of these bus interfaces are transmitted separately. At the receiving end, the clock signal is processed and then used to receive data synchronously, resulting in the connection port At least two wires are required. In the connection scheme of multiple bus devices, additional connection ports are required, occupying a larger system area, making the ports of the system complex and increasing the cost of the system. Contents of the invention [0003] In order to solve the above technical problems, the present invention discloses a single-bus transmission method, which includes: [0004] After receiving the system start signal, the encoding control mod...
