Abstract:
A system and method to organize and use data sent over a double data rate interface so that the system operation does not experience a time penalty. The first cycle of data is used independently of the second cycle so that latency is not jeopardized. There are many applications. In a preferred embodiment for an L2 cache, the system transmits congruence class data in the first half and can start to access the L2 cache directory with the congruence class data.
