Control device for a buffer memory with reconfigurable partitioning

Claim 1

Control device for a buffer memory for storing information comprising: reconfigurable partitioning means for distinguishing two types of information, an "instruction" type and a "data type"; and replacement means which replace stored information with current information according to at least one replacement algorithm, in which the partitioning means control at least one of the information types, therefore called a controlled type of information; a memory for storing a value corresponding to a predetermined reference amount of memory greater than zero scattered in the buffer memory, allocated to the controlled type of information, the control means including means for storing a value corresponding to the amount of controlled type information previously stored, and comparing the amount of information of the controlled type previously stored in the memory with the predetermined reference amount, prior to storing current information and if it exceeds the predetermined reference amount, when a current information item has to be loaded while said reference amount of memory has been exceeded by the stored information of controlled type, the replacement means load it by priority by replacing a stored replaceable information item of controlled type of information.
