Micromega uM-FPU64 64-bit Floating Point Coprocessor     $19.95
ea.  Not wimpy 16-bit, or even anemic 32-bit - this match chip
does 64-bit math while expanding the I/O capabilities of your
design.  Description [Hide]  Doing GPS navigation? MEMS-based
sensor calculations? 32-bit floating point number calculations
may not be sufficient. If you're after greater precision, try
the The uM-FPU64 coprocessor, with support for both 32-bit and
64-bit floating point numbers.  You might be an super-programmer
that can work these calculations into an 8-bit platform, but you
won't be able to do it as quickly as a dedicated module can, and
as it talks SPI or I2C, you'll be able to talk to practically
any micro platform. As software match libraries can chew up your
micro's memory rather quickly, you'll be better off using an uM-
FPU64 to take care of the heavy-lifting math tasks. And as it
also features FFT, matrix operations and NMEA sentence parsing
capabilities, you'll be set for future calculations.  Want to
