Abstract

A bus interface device and method for matching optical modules. The device is connected to the bus, and includes: a bus matching unit, which performs a control operation with the bus interface, and outputs digital data and control signals of the interface device to the bus; an optical matching module, including a sending terminal for converting digital signals into optical signals, and a receiving terminal for converting an input optical signal into a digital signal; a matching controller delaying a signal exchanged between the bus matching unit and the optical matching module for a predetermined period. It solves the inconvenience of not being able to transmit correct data due to time delay during signal conversion, and improves the overall performance of the system.

Description

technical field [0001] The present invention relates generally to bus protocols, and more particularly to methods and apparatus for bus interfaces modified to match optical modules. Background technique [0002] In the field of information processing technology, where high speed and miniaturization are important, there are special complications. First, the processing speed of peripheral circuits such as memory, cache memory, and chipset cannot keep up with the speed of high-speed processors. This prevents the processor from performing to its full potential. In addition to this problem in processing speed, there are problems such as noise and electromagnetic interference (EMI). Although the amount of noise and EMI generated in digital and analog circuits is different, these factors all cause problems in the operation of digital and analog circuits or systems, and also bring difficulties to users and developers. [0003] One way to solve these problems is to use optical med...
