uM-FPU V3.1 Floating Point Coprocessor |
The uM-FPU V3.1 Floating Point Coprocessor chip. The new chip extends the feature set of the original uM-FPU V3 chip to include serial I/O support, NMEA sentence parsing, block transfers, additional matrix operations, enhanced string support, and many other enhancements.
See the uM-FPU V3.1 product page for full details. |

uM-FPU V3 Integrated Development Environment (IDE)
|
 |
|
The uM-FPU V3 IDE (Integrated Development Environment) makes it easy to develop uM-FPU V3 code, by providing a code generator, debugger and function programmer.
The code generator takes traditional math expressions and automatically produces uM-FPU code for any one of the many microcontrollers and compilers supported. The debugger lets you step through uM-FPU code to trace instruction execution and display register values. The function programmer provides support for storing user-defined functions in Flash memory.

The uM-FPU chip is featured in an article by Jon Titus in the March 19, 2007 edition of Design News magazine. The article entitled, Micromega Chip Does the Math provides an excellent overview of the uM-FPU floating point coprocessor.
If you've read the article and are looking for more information, there's lots of information here. See the
products page for product information, and the
downloads
page for documentation and software.
Also, check out the
uM-FPU V3 Integrated Development Environment (IDE), and browse through the
Application Notes for additional information and some interesting examples.
