ABSTRACT:
A system uses specialized software instructions for efficient management of freelists. In a preferred embodiment, special load and store instructions are provided. The load instruction is mapped to a register or memory location. When the load instruction is performed, hardware uses a bit-map free slot map to return an index of a free slot. Similarly, the store instruction is used to release, or free, a slot. The store instruction allows software to specify an index of a slot to be freed.
