Abstract

A system for real-time operating system memory block and message management is disclosed. The real-time operating system enables different processes to migrate an allocated memory block from one type of memory block to another type of memory block, and to reliably release the block back to its correct pool of origin. According to one aspect of the inventive subject matter, a memory management engine allocates memory in a basic type to a first process, and upon a migration request from a second process, convert the allocated memory from the basic type to a message type for the second process. Allocating memory in the basic type can be fast but does not ensure proper release of the memory block to its pool of origin. Converting the basic type to the message type enables the operating system to reliably release the block back to its correct pool of origin from any process.

Claims25

Dependent claims

A memory block management system comprising:

a first memory storing a memory block pool, wherein each of the at least one memory block pool comprises at least one memory block;
a second memory storing memory management instructions within an operating system;
and
a processor coupled with the first and the second memory, and programmed to execute the memory management instructions of:
obtaining, via the operating system, a memory block from the at least one memory block pool;
initializing the memory block as a first type of memory block according to a corresponding first request issued from a first instruction calling layer;
migrating the memory block, via the operating system, from the first type of memory block to a second type of memory block according to a second request issued from a second, different instruction calling layer;
and
releasing the memory block to the memory block pool according to a third request associated with the second type of memory block.
