Apparatus and method for compressing a plurality of contiguous addresses to form a compressed block address using the first address of the contiguous addresses and a block identifier bit

摘要

A method for compressing a plurality of contiguous addresses for storage in a queue. The method includes recognizing that a first address of the plurality of addresses is an individual address that corresponds to a memory location that is transferred individually. A first value of a block identifier bit is associated with the first address, with the first value identifying the first address as an individual address. The first address and the first value of the block identifier bit are stored into the queue. A further address of the plurality of addresses is recognized as a block address corresponding to a plurality of contiguous data words that reside at a respective plurality of contiguous addresses, that begin with the further address, and that are transferred as a block unit. A second value of the block identifier bit is associated with the further address, the second value identifying the further address as a block address. The second value of the block identifier bit and only the further address of the plurality of contiguous addresses are stored into the queue, thereby compressing the plurality of addresses stored in the queue.
