4.6.2. VFP architectures

VFP is a floating-point architecture that provides both single and double precision operations. Many operations can take place in either scalar form or in vector form. Several versions of the architecture are currently supported, including:

Note

Particular implementations of the VFP architecture might provide additional implementation-specific functionality. For example, the VFP coprocessor hardware might include extra registers for describing exceptional conditions. This extra functionality is known as sub-architecture functionality. For more information about sub-architecture functionality, see ARM Application Note 133 - Using VFP with RVDS. You can find this application note in the vfpsupport sub-directory of the Examples directory of your RVDS distribution at install_directory\RVDS\Examples\...\vfpsupport.
