Abstract
In one embodiment, a processor may be configured to write ECC granular stores into the data cache, while non-ECC granular stores may be merged with cache data in a memory request buffer. In one embodiment, a processor may be configured to detect that a victim block writeback hits one or more stores in a memory request buffer (or vice versa) and may convert the victim block writeback to a fill. In one embodiment, a processor may speculatively issue stores that are subsequent to a load from a load/store queue, but prevent the update for the stores in response to a snoop hit on the load.
