- The Apple Neural Engine (ANE) is a fixed-function matrix accelerator used in Apple chips like the A11-A18 and M1-M5 families.
- It's exposed to applications only through the Core ML model framework, but can be accessed directly for measurement and research purposes.
- The guide covers architecture details including datapath, roofline analysis, compiler, weight-compression, and kernel driver.
- Claims are categorized as measured, decompile-derived, or predicted, with methodology and open questions documented.
- Direct measurements were performed on M1 and M5 chips to validate performance and energy efficiency.
