Title |
The effect of interconnect design on the performance of large L2 caches |
Date |
2006 |
Description |
The ever increasing sizes of on-chip caches and the growing domination of wire delay have changed the traditional design approach of the memory hierarchy. Many recent proposals advocate splitting the cache into a large number of banks and employ an on-chip network to allow fast access to nearby banks (referred to as Non-Uniform Cache Architectures (NUCA)). While these proposals focus on optimizing logical policies (placement, searching, and movement) associated with a cache design, initial design choices do not include the complexity of the network. With wire delay being the major performance limiting factor in modern processors, components designed without including wire parameters and network overhead will be sub-optimal with respect to both delay and power. The primary contributions of this work are: 1. An extension of the current version of CACTI to include network overhead and find the optimal design point for large on-chip caches. 2. An evaluation of novel techniques at the microarchitecture level that exploit special wires in the L2 cache network to improve performance. |
