Anadigm®'s
field programmable analog arrays (FPAAs) and
design software introduce two new capabilities
to the analog world. The first is the ability
to translate complex analog circuits to a
simple set of low-level functions, and thus
to give designers the analog equivalent of
an FPGA. The second is the ability to place
analog functions under real-time software
control within the system.
By
providing the analog equivalent of logic
gates, FPAAs give designers the ability
to describe analog functions such as gain
stages and filters without reference to
the underlying function - in other words,
without having to think on the level of
such components as op amps, capacitors,
resistors, transconductors, and current
mirrors. Lifted to this higher level of
abstraction, the design process becomes
so simple that non-specialists can created
sophisticated circuits that would require
weeks or months of design work with ASICs
or discretes.
Dynamic
configurability adds to these capabilities
by allowing analog functions to be updated
in real time using automatically generated
C-code. With analog functions under the
control of the system processor, new device
configurations can be loaded on the fly,
allowing the device's operation to be "time-sliced,"
or to manipulate the tuning or the construction
of any part of the circuit without interrupting
operation of the FPAA, thus maintaining
system integrity.
