Floating point library How-To

Package Contents:
- float_lib.dll :  dll implementing VFP accelerated
                floating point operations
- VFPLoader.dll: Shim dll for replacing coredll floating point functions
                  with VFP implementation 
- vfpload.exe:  Executable that loads shim into running system


VFP Enabling a system:
1. Place float_lib.dll, VFPLoader.dll, and vfpload.exe at \Windows are the target system
2. Launch vfpload.exe

Note:  The mechanism for inserting the VFP implementation (noted above) of the floating point functions 
       must have been launched before any applications that need to be accelerated are launched.  This 
       can be acheived by including the VFP files from this package in the run-time image and launching 
       the vfpload.exe at boot time via a registry entry.
