Offline Routing and Wavelength Assignment in Transparent WDM Networks
We consider the offline version of the routing and wavelength assignment (RWA) problem in transparent all-optical networks. In such networks and in the absence of regenerators, the...

Circuit design of a dual-versioning L1 data cache for optimistic concurrency
This paper proposes a novel L1 data cache design with dualversioning SRAM cells (dvSRAM) for chip multi-processors (CMP) that implement optimistic concurrency proposals. In this n...
