Virtual memory mapping for efficient memory usage

A system comprising:

• a processing component configured to:
• map a first virtual address associated with first data to a first page of physical memory, the first page having a predetermined page size corresponding to the smallest partition of memory mappable by the processing component from virtual addresses to physical addresses;
• and
• allocate a first sub-block of physical memory resident in the first page for storing the first data, wherein the first sub-block is selected from a set of sub-blocks having sub-blocks of at least two different sizes, and wherein the first sub-block has a size smaller than the predetermined page size.

• allocate a first sub-block of physical memory resident in the first page for storing the first data;
• map a second virtual address associated with second data to the first page;
• and
• allocate a second sub-block of physical memory resident in the first page for storing the second data,
• wherein the first and second sub-blocks have sizes smaller than a predetermined page size, and
• wherein the size of the first sub-block and the size of the second sub-block are different.
