> Apple is currently looking for experienced programmers with detailed knowledge of the RISC-V Instruction Set Architecture (ISA) and Arm's Neon vector ISA for its Vector and Numerics Group (VaNG) within its Core Operating Systems group. Apple's VaNG is responsible for developing and improving various embedded subsystems running on iOS, macOS, watchOS, and tvOS.
The Job description even goes on to the task.
>The programmer will work in a team that’s “implementing innovative RISC-V solutions and state of the art routines. This is to support the necessary computation for such things as machine learning, vision algorithms, signal and video processing,” the job description says.
This is specific to RISC-V Vector Extension. And specific to certain type of workload.
