Ideally caches act as magic make-it-go-faster logic sitting between processor cores and memory banks. But there are cases where cache behaviour must be considered to get the desired result.

This is the first part of a series on how to write SIMD code for Neon using assembly language. It covers getting started with Neon, using it efficiently, and more.

Sitting in the airport at the end of a week's business trip to the US, I reflected back on the week.  It turned out that my colleague on this trip has an even worse sense of direction than myself.…

In this post, we deal with an often encountered problem: input data that is not a multiple of the length of the vectors you want to process.

Arm implements conditional execution using a set of flags which store state information about a previous operation. in this post I shed some light on the operation of these flags.

This post will show you how we can deal with these limitations and how the latest revision of the Arm architecture (Armv7) provides a simple and efficient solution.

In this post, we will look at how to efficiently multiply four-by-four matrices together, an operation frequently used in the world of 3D graphics.

This blog is a tutorial on detecting overflow from MUL.

It was always about the code (and where it would be used!) When I was a software developer I would often find that the project team I was in would try to guess how many devices the code would eventually…
