Method for a memory organization by physical zones in a computerized or data processing machine or arrangement and the computerized or data processing machine or arrangement for using the method

A data processing system comprising:

• a physical memory that is divided into a plurality of physical memory zones, each having physical pages assigned to contiguous physical page numbers;
• a list, for each of said memory zones, of available physical pages among said physical pages in the corresponding physical memory zone;
• at least one process executed by the data processing system and requesting an allocation of at least one available physical pages in one of said memory zones;
• a name determined by said at least one process for said one memory zone in order to distinguish it from the other ones;
• means for performing a first function, said first function including the steps of verifying whether at least one of said physical pages is available in said one memory zone and, if no page is available as a result of said verifying step, placing said at least one process in a queue that corresponds to said one memory zone;
• and
• means activated if at least one page is available as a result of said verifying step for performing a second function, said second function extracting a physical page number from said list of available pages in said one memory zone for use by said at least one process.

A method for allocating physical memory to at least one computing process executed in a data processor system having a physical memory that is divided into a plurality of physical memory zones, each having physical pages assigned to respective, contiguous physical page numbers, said method comprising the steps of:

• defining, for each of said memory zones, a list of available physical pages from said physical pages in each of said memory zones;
• requesting, from said at least one process, allocation of at least one available physical page in one of said memory zones;
• determining, by said at least one process, a name for said one memory zone in order to distinguish it from the other memory zones;
• activating a first function, said first function performing the steps of verifying whether at least one of said physical pages is available in said one memory zone and, if no page is available as a result of said verifying step, placing said at least one process in a queue that:
• corresponds to said one memory zone;
• and
• activating a second function if at least one page is available as a result of said verifying step, said second function comprising the step of extracting a physical page number from said list of available pages in said one memory zone for use by said at least one process.
