The
Fujitsu FR (Fujitsu
RISC) is a
32-bit RISC processor family. New variants include a
floating point unit
Floating may refer to:
* a type of dental work performed on horse teeth
* use of an isolation tank
* the guitar-playing technique where chords are sustained rather than scratched
* ''Floating'' (play), by Hugh Hughes
* Floating (psychological ...

Applications
Fujitsu FR are used to control previous versions of
Milbeaut signal processors specialized for
image processing. Although variants of the 6th generation in 2011 and later generations changed to
dual-core
A multi-core processor is a microprocessor on a single integrated circuit with two or more separate processing units, called cores, each of which reads and executes program instructions. The instructions are ordinary CPU instructions (such ...
