Abstract
A mechanism is disclosed for offset-based addressing in the chunks of a chunked heap. The mechanism provides for storing a side data structure within a portion of a chunk, where the side data structure begins at a predetermined offset within the range of virtual memory addresses allocated to the chunk. The side data structure comprises a plurality of entries, where each entry is associated with a corresponding section of the chunk. The mechanism provides for locating a particular entry in the side data structure corresponding to a particular section of the chunk by using the predetermined offset and an index derived based on the particular section, where locating the particular entry does not include performing any memory accessing operations or conditional branch operations to obtain an indirect reference to the side data structure.
