GoFast® for 80x86 Protected Mode (GF-PROT)
Fast Floating Point Library
Features
- Fast
- Reentrant
- ROMable
- Conforms to IEEE 754
- Includes test programs and make file
- Source code provided
Description
GoFast® for 80x86 Protected Mode is a floating point emulator for the 80386
and i486SX 32-bit protected mode. GF-PROT supports any 80x86 protected mode
processor, which does not contain floating point support in the processor. GoFast
provides ROMable, reentrant IEEE and ANSI compatible 80x86 floating point support.
Functionality
GF-PROT matches the functionality of the 80387 coprocessor. GF-PROT gets
control through interrupt 7 (coprocessor not present). The GoFast code will then run
and process the floating point instruction in software just as the instruction would have
been handled in hardware had a floating-point coprocessor been present.
Environment
GoFast for Microsoft C will operate in either a DOS extender environment or an
embedded environment. Flat model and segmented model library versions are provided.
GoFast Support
U S Software maintains a test lab where comprehensive confidence tests are
performed on GoFast in each target environment. A demonstration test program
included with your product delivery, and you are encouraged to run it on your own
hardware to verify system operation. Phone and fax support are provided with the
product. Extended support is also available.
