Arm Floating-Point Instructions

Abstract

The first Arm Floating-Point Accelerator, which appeared in 1993, resembled the x87 coprocessor in its use of an 80-bit EP register file. This was succeeded by the Vector Floating-Point (VFP) architecture, which included 64-bit registers implementing the single-, double-, and half-precision data formats. The NEON Advanced SIMD extension later added 128-bit instructions for media and signal processing applications.
