demanding applications, and can offload the floating point
calculations from the microcontroller.
The uM-FPU64 is compatible with the instruction set
of Micromega’s popular uM-FPU V3.1 32-bit floating point
coprocessor. Advanced instructions are provided for fast
data transfer, matrix operations, FFT calculations, serial
input/output, NMEA sentence parsing, string handling,
digital input/output, analog input, and control of local
devices.
Local device support includes: RAM, 1-Wire, I2C, SPI,
UART, counter, servo controller, and LCD devices. A built-in real time clock and foreground/background processing
is also provided. The uM-FPU64 can act as a complete
subsystem controller for sensor networks, robotic
subsystems, IMUs, and other applications.
The uM-FPU64 IDE (Integrated Development
Environment) makes it easy to create, debug, and test
code. Code can be written in the IDE’s high level language
or in assembler, then compiled to generate code targeted
for one of the many microcontrollers and compilers
supported, or it can be stored internally in Flash memory.
The IDE provides support for editing code, compiling,
tracing code execution, setting breakpoints, examining
registers, and programming user-defined functions in Flash
memory.
The uM-FPU64 chip is RoHS compliant and has an
operating voltage of 3.3V, with 5V tolerant SPI and I2C
interfaces. SPI interface speeds up to
15 MHz and I2C interface speeds up
to 400 kHz are supported. The chip is
available in PDIP- 28, SOIC- 28, or
TQFP- 44 packages. The single unit
price is $24.95 with volume discounts
available.

“AUV competitions
such as Robo-Magellan
are the most exciting and
relevant because of their
outdoor all-terrain
unpredictable nature,
which is a lot like reality,”
according to Mike
Marzetta, MINDS-i
inventor. “In contrast,
many of today’s more
popular robot
competitions
unfortunately still take
place on tabletops and
gymnasium floors. I have never seen a photo of the
surface of Mars with a flat paved surface waiting
