ABSTRACT:
An improved data structure is provided by modifying a public-domain data structure known as a “heap”. When these improvements are applied, the resultant data structure is known as a “pile.” This invention further described a pipelined hardware implementation of a pile. Piles offer many advantages over heaps: they allow for fast, pipelined hardware implementations with increased throughput, making piles practical for a wide variety of new applications; they remove the requirement to track and update the last position in the heap; they reduce the number of memory reads accesses required during a delete operation; they require only ordinary, inexpensive RAM for storage in a fast, pipelined implementation; and they allow a random mixture of back-to-back insert, remove, and swap operations to be performed without stalling the pipeline.
