Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Embodiments of the present invention propose a method similar to I 2 The bus structure of C can transmit data in parallel through bus expansion, respectively supporting 8-bit, 16-bit and 32-bit parallel data, which greatly improves the data transmission speed. The name of the bus is INC (Inter N bit Connection), which means interconnecting N bits bus. Embodiments of the present invention will be described in further detail below in conjunct...

Abstract

The embodiment of the invention discloses a bus structure for interconnecting a microcomputer with peripheral equipment. The bus structure consists of a clock line SCL (Serial Clock Line) and N data lines SDA (Serial Data Line), wherein the number of the data lines is selected according to the actual requirements; the total width of the bus structure is N+1; and the peripheral equipment is connected with a host CPU (Central Processing Unit) by the N data lines and one clock line of the bus structure. By the bus structure, the parallel and bidirectional transmission of N bits of data is implemented; and the data lines are expanded so that the data transfer rate can be multiplied.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a bus structure for interconnecting microcomputers and peripheral devices. Background technique [0002] At present, there are many buses used to connect microcomputers and peripherals. The most common parallel buses of microcomputers include data bus, address bus and control bus (read, write, enable, chip select, direction indication, valid address, etc.); Row bus includes I 2 C, SPI, USB, SATA, etc. [0003] Among them, I 2 The C (Inter-Integrated Circuit, two-wire interconnection bus between integrated circuits) bus is a common bus used to connect CPUs and peripheral devices. 2 The C bus realizes data transmission through two connecting wires, and the circuit is the simplest; multiple peripherals can be connected at the same time, and peripheral access is distinguished according to different addresses; but the I2C bus in the prior art can only transmit data throug...
