The ARM NEON Extensions
This chapter begins with an overview of the NEON extensions and explains the relationship between VFP and NEON. The NEON registers are explained, and the syntax for NEON instructions is explained. Next, each of the NEON instructions are explained, with short examples. In some cases, extended examples and figures are provided to help explain the operation of complex instructions. After all of the instructions are explained, another implementation of sine is presented and compared to previous implementations and with the GCC sine function. It is shown that NEON gives a significant performance advantage over VFP and hand coded assembly is much faster than the sin function provided by the compiler.
