Title:
DECODING METHOD AND APPARATUS OF TRANSMISSION PROTOCOL AND TRANSMISSION PROTOCOL DECODING CHIP
Document Type and Number:
WIPO Patent Application WO/2015/058473
Kind Code:
A1
Abstract:
The present invention is applicable to the field of communications, and provided are a decoding method and apparatus of a transmission protocol and a transmission protocol decoding chip. The method comprises the steps of: generating an oscillator signal; detecting a frame start signal, and outputting a sampling control signal when the frame start signal is detected; after receiving the sampling control signal, counting the number of oscillation periods of the oscillator signal in a time period of a low level digit of a frame start byte, and performing division calculation on a count value and outputting a quotient and a remainder; and determining a sampling period according to the quotient and the remainder, so as to generate a sampling pulse, and decoding a data byte according to the sampling pulse. The present invention counts the number of oscillation periods of an oscillator signal in a time period of a low level digit of a frame start byte, performs division calculation on a count value, outputs a quotient and a remainder and performs decoding according to the quotient and the remainder, so that there is no accumulation error, the decoding accuracy rate is improved greatly, and it is simple to implement and has a low cost and good stability.
