Abstract
Sequential write operations to a unit of compressed memory, known as a compression tile, are examined to see if the same compression tile is being written. If the same compression tile is being written, the sequential write operations are coalesced into a single write operation and the entire compression tile is overwritten with the new data. Coalescing multiple write operations into a single write operation improves performance, because it avoids the read-modify-write operations that would otherwise be needed.
