highly cited). This was the first paper proposing a Dynamic (Hardware) Neural Branch Predictor. Recently the idea of neural branch prediction was implemented in some commercial processors like Oracle Sparc T4-4 (2011), AMD Bobcat/Jaguar (2014), Samsung Exynos M1 Processor (2016; my paper is cited !), AMD Ryzen (2017), etc.
