A SysCall to ARMs presented at DerbyCon 2013

by Brendan Watters,

Summary : ARM processors are growing more and more prevalent in the world; ARM itself claims that more than 20 billion chips have been shipped. Take a moment to appreciate that is about three chips for every man, woman, and child on earth.
The three main topics I aim to cover are (1) how to perform a Linux system call on an ARM processor via assembly, ARM pipelining used in most modern ARM processors and how it came about, and (3) the really cool way ARM can avoid branching, even with conditional control flow. These will be explained in both code, English, and (hopefully successful) live demos using an ARM development board. The end result is to get the audience to understand how to create a simple socket program written in ARM assembly.
