The emphasis in microprocessor design has shifted from high performance, to a combination of high performance and low power. Until recently, this trend was mostly true for uniprocessors. In this work we focus on new energy consumption issues unique to multiprocessor systems: synchronization of accesses to shared memory. We investigate and compare different means of providing atomic access to shared memory, including locks and lock-free synchronization (i.e., transactional memory), with respectdoi:10.1109/lpe.2005.195542 fatcat:ohnr3nfnijgabgivvyeipmgcfu
