Abstract
The present disclosure generally relates to a method and system for efficiently sharing limited memory among multiple processors. Each processor has a local linked list. The local linked list identifies the pages allocated to the specific processor as well as the number of free codewords for each allocated page. Additionally, the local linked list includes the location of the next free codeword(s) for each allocated page. When all codewords are available, the page is considered free and may be sent back to the page pool used by all of the processors. If there are a sufficient number of contiguous free codewords on an allocated page, then new codeword data may be stored in the page. If there is not a sufficient number of contiguous free codewords on any allocated page, then a new page is allocated from the page pool. Thus, efficient allocate of memory resources is achieved.
