Abstract
A method and apparatus for memory allocation in a multi-processor system is accomplished by mapping portions of a shared memory to a first and second processor. The mapping is performed such that either of the processors' portions can be enlarged or reduced based on the memory that is located between the portions allocated to the processors. When a processor requests additional memory and there is sufficient free memory between the processors' respective portions, the appropriate amount of the free memory is allocated to the requesting processor.
