The detection crushing clinical in a buffer memory, in particular for a switch of clinical

摘要

The field of the invention is that of the systems of the management of access to a memory for storing data to be limited capacity, by a write device and by a reading device independent. / p & & p & the objective is to provide a system which prevents the microprocessor management of a task of monitoring the state of filling of the buffer memory, in particular in the case of a buffer memory 22 of the lines of reception, in a data switch. / p & & p & according to a preferred embodiment of the invention, the system comprises first means 42, 45 of the description of the state of the availability of the memory writing, said means of the description of the availability 42, 45 are updated by means of reading the data in the memory 22, and second means 42, 45 of the description of the validity of the data of the memory, said means of the description of validity, 42, 45 are updated by means of writing of data in the memory 22 as a function of the means of the description of the state of availability, 42, 45 at the time of writing.
