Using Switch Directories to Speed Up Cache-to-Cache Transfers in CC-NUMA Multiprocessors
In this paper, we propose a novel hardware caching technique, called switch directory, to reduce the communication latency in CC-NUMA multiprocessors. The main idea is to implemen...

On entropy rate for the complex domain and its application to i.i.d. sampling
We derive the entropy rate formula for a complex Gaussian random process by using a widely linear model. The resulting expression is general and applicable to both circular and non...
