MIPS Floating Point Accelerator (FPA) chip
(now, usually part of the processor chip)
has a condition bit that is set to
to indicate if a condition is false or true.
Several FPA instructions affect this bit and
several CPU instructions test this bit.
Are the FPA (floating point accelerator) and coprocessor 1 the same?
