FPEmulator sources opened by ARM Ltd.
Steve (ROOL)
code supplied by ARM Ltd. (ARM). This source code has been published as Open
Source software under the New BSD licence and it comprises the FPA support
code (FPASC) and emulator (FPE).
The FPE is a key part of the RISC OS operating system and as such the
availability of these components in source form is a key step towards
completing the publishing of the full sources to RISC OS. You can find the
new FPASC source code within the ROOL CVS repository as part of the
FPEmulator module.
Until now, the FPASC and FPE have only been available to the public in
binary form. This is equally true for other operating systems, such as the
BSD derivatives. ROOL will be contacting the maintainers of various ARM BSD
projects in due course.
Note to editors: this press release does not constitute an endorsement of
RISC OS or of the FPE by ARM.

About RISC OS Open
RISC OS Open (ROOL) is an organisation run on a largely voluntary basis. We
are managing the process of publishing the source code to RISC OS and its
further development. We also offer professional services to anyone who is
interested in developing commercial products using RISC OS, or in other
related fields.
About the FPEmulator module
The RISC OS FPEmulator module is a core component of the operating system
which provides support for floating point instructions used by many of the
applications and modules you encounter every time you use your machine.
The source code released by ARM comprises an OS-independent 'core'
functionality. This needs to be linked to OS-specific code to handle
configuration of the core and interfacing it to the host OS's exception
dispatch, error handling, context switching, memory management and system
call interfaces. The OS-specific code for RISC OS also forms part of the
FPEmulator module, and has been provided by Castle Technology Ltd under the
same shared source licence as the bulk of the RISC OS source code.
