30.10.2.7. ARM processor documentation
ARM also releases documentation specific to each given processor.
This adds extra details to the more portable ARMv8 architecture reference manual ISA documentation.
For every processor, there are basically two key documents:
-
technical reference manual, e.g.: Arm Cortex‑A77 Technical Reference Manual r1p1
-
software optimization guide, e.g.: Arm Cortex‑A77 Software Optimization Guide r1p1
This contains some approximate instruction latencies and pipeline properties.
