Chapter 5 examines the scalar floating-point capabilities of Armv8-32. It begins with a section that explains important floating-point concepts including data types, bit encodings, and special values. Software developers who understand these concepts are often able to improve the performance of algorithms that make heavy use of floating-point arithmetic and minimize potential floating-point errors. The next section describes the Armv8-32 floating-point architecture. It begins with an overview of the Armv8-32 floating-point register file and its overlapping ...
