Abstract :
The NoSQ microarchitecture performs store-load communication without a store queue and without executing stores in the out-of-order engine. It uses speculative memory bypassing for all in-flight store-load communication, enabled by a 99.8 percent accurate store-load communication predictor. The result is a simple, fast core data path containing no dedicated store-load forwarding structures
