Abstract

The invention provides a self-adaptive serial clock sequence detection device and detection method. The device comprises a clock sequence, the clock sequence is connected with a COM character detection module, the COM detection module is connected with a PCIe clock sequence detection unit, the PCIe clock sequence detection unit is connected with a RapidIO clock sequence detection unit, and the RapidIO clock sequence detection unit outputs a detection result. According to the invention, serial detection of two protocol clock compensation sequences of RapidIO and PCIe can be realized; a detection module string is automatically selected according to different clock compensation sequences, a non-current protocol detection module is closed at the same time, the input of the non-current protocoldetection module is blocked, and the influence caused by a small probability event of another protocol clock compensation sequence in a data stream is avoided; according to the invention, when the clock compensation sequence is detected, the indication of the corresponding protocol is given, so that the module connected with the clock compensation sequence can be conveniently modified towards theadaptive hardware direction.

Description

technical field [0001] The invention belongs to the technical field of clock sequence detection, and in particular relates to an adaptive serial clock sequence detection device and method. Background technique [0002] RapidIO technology is mainly oriented to the interconnection communication of high-performance embedded systems, and its transmission efficiency is higher than that of Ethernet. Moreover, due to the comprehensive consideration of RapidIO routing, switching, error tolerance and error correction, and ease of use, it can achieve high-performance and reliable data transmission based on hardware. [0003] PCI Express (PCIe) is a bus that can be applied to the interconnection of all peripheral I / O devices such as mobile devices, desktop computers, workstations, servers, embedded computing and communication platforms. [0004] Both can use serial links for high-speed transmission. The physical layers of the two protocols have a high degree of similarity, and can be...
