The ideal candidate will enjoy working across our ANE hardware and software architecture to achieve this, and have a passion for squeezing the best possible performance out of the ANE hardware.\nDescription\nImplement new functional features in the compiler stack using Apple Neural Engine simulation environment, with an emphasis on performance and power.\nDrive performance content delivery to the hardware team and triage functional issues.\nCollaborate with the hardware team to review hardware specifications.\nWork closely with the design and micro-architecture team to understand the functional and performance goals of the design.\nParticipate in workload selection and preparation of the ANE functional and performance test plan.\nDeep-dive into hardware investigations to understand and root-cause performance gaps.\nEvaluate new hardware features and contribute to the definition of architectural changes for future ANEs.\nDevelop features for future products, bringing those features from initial concept, through development, leading to hardware bringup and validation.\nPartner with the driver/firmware teams to integrate HW acceleration in our software stack.\nCollaborate more broadly with hardware design, verification, performance and architecture teams within our Silicon Engineering
