Apropos of Apple’s ARM announcment, I thought I might write up a post on a recent bit of code I wrote that specifically looks at ARM64, and its benchmarks on various hardware. I’ve been implementing some compact data structures for a project. One of the CPU hotspots for the implementation is the need to run a quick population count across a potentially large bit of memory.
