A method and an arrangement for adjusting the regimen to which information is read data from a Memory, the Regime which writes the information of the data in the memory.

摘要

The present Invention relates to the technical field of Memory Storage and digital teletransmission and, more particularly,A method and an arrangement for Writing data into a Memory (FIFO) and read the data in the same way that the reading system is, on average,As high as the writing System. The Frames of input (Data in) and other information (Other). Only the information of the data will be written to the memory.A Generator (radrgen) writing direction generates a cyclic sequence of writing directions for each Information Unit of Data that happen to be written into the memory.A cyclic sequence of Reading direction is generated by a Generator (wadrgen) direction of Reading for reading information from the memory.The provision also includes a Synchronous Circuit of Phase Locked Loop (PLL) works for the system adjusted to adjust the reading scheme which generates the addresses of Reading.According to the invention, means are provided for Detecting a Frame arrives to the memory (FIFO) contains a Greater or Lesser number of Information units of number of nominal Data.If the frame contains a Greater or Lesser number of units of Data Information, this Masks initially for the Circuit of Phase synchronization.Changing a First direction (a) of reference so that the Synchronous Circuit of Phase Locked Loop (PLL) do not change the Regime which momentarily generate addresses Reading.The mask is then removed in incremental Steps through which the circuit synchronization Phase corresponds to the scheme to which are generated by stages of Reading directions, i.e.The system of Reading. This prevents the Circuit of Phase synchronization takes place rapidly regime changes are very large.
