Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] There are digital clock management units (called DCM by xilinx company and DLL by ALTERA company) inside most programmable logic devices. The Digital Clock Management Unit provides powerful internal and external time management functions for programmable logic devices. It not only supports precise phase shift and frequency synthesis control, but also provides zero-latency clock buffering, while controlling the clock signal to achieve high precision. In addition, the digital clock management unit can flexibly manage internal clocks and external clocks through user input data.

[0027] see Figure 4 , which is a flow chart of a method for adjusting delay inconsistency of received data by using an associated clock signal provided by the present invention. It is used for the receiving end to correctly receive the data sent by the sending end, and the sending en...

Abstract

A method for resolving the inconsistency of the delay of received data by associated clock signals includes: 1, the sending end sends a fixed training sequence to a receiving end via data lines and sends associated clock signals to the receiving end via the associated clock line, in which, said fixed training sequence is agreed to be the exclusive one in the sending period by the two ends in advance, 2, said receiving end triggers the data collection by the associated clock signal and judges if the received data are the same with said fixed training sequence, if so, the phase is locked and the sending end sends the data to the receiving end at the same time, otherwise, the receiving end regulates the received clock phase by the local data clock management unit then to step 1.

Description

technical field [0001] The invention relates to the field of wireless communication networks, in particular to a method for adjusting the delay inconsistency of received data by using an associated clock signal. Background technique [0002] see figure 1 , which is a schematic diagram of the principle structure of data communication between two pieces of hardware. Wherein, not only a data communication connection is established between the sending end 1 and the receiving end 2 , but also the sending end 1 sends the channel-associated clock signal of the own end to the receiving end 2 . The associated clock signal is used to adjust the receiving end 2 to correctly receive the data sent by the sending end 1 . Wherein, the two pieces of hardware for data communication (sending end 1 and receiving end 2) may be hardware devices or hardware boards. [0003] In the process of data communication between the sending end 1 and the receiving end 2, the delay of the associated clock...
