Micromega has released software and documentation for using the uM-FPU
V3.1 floating point coprocessor with the ARMmite and ARMexpress
controllers. Details can be found at:
http://www.micromegacorp.com/armbasic.html

Advanced instructions and fast execution allows the uM-FPU V3.1 chip
to handle data from a wide range of sensors, and perform the
additional computations or data transformations required to provide
the most accurate results.

Reading GPS data is easy with the uM-FPU V3.1 chip using the new NMEA
sentence parsing capabilities. An added advantage, is that the GPS
data is then already loaded on the FPU, ready for navigation
calculations. For an example, see Application Note 39.

It's been updated with an ARMmite/ARMexpress example that calculates
great circle distances.

The uM-FPU V3 IDE software, which automatically generates uM-FPU V3.1
code from math expressions, supports ARMbasic code generation.

Micromega has released software and documentation for using the uM-FPU
V3.1 floating point coprocessor with ARMbasic Version 7. Details can be
found at:
http://www.micromegacorp.com/armbasic.html

The new parameter passing and function return capabilities in V7 makes
the code easier to read and implement. There's an additional document
called 'V6 to V7 conversion' that describes the steps needed to convert
existing V6 code to use the new V7 support.

With the uM-FPU V3.1 chip it's easy to add floating point support to
ARMexpress/ARMmite projects. An overview of the uM-FPU V3.1 chip can be
found at:

An added feature of the uM-FPU V3.1 chip is the ability to directly read
and parse data from a serial GPS device. It's a great way to add GPS
capabilities and navigation calculations to an ARMexpress/ARMmite
project.
