Neurobiology research suggests that information can be represented
by the location of an activity spot in a population of cells (place
coding'), and that this information can be processed by means of
networks of interconnections. Place Coding in Analog VLSI defines a
representation convention of similar flavor intended for
analog-integrated circuit design. It investigates its properties
and suggests ways to build circuits on the basis of this coding
scheme. In this electronic version of place coding, numbers are
represented by the state of an array of nodes called a map, and
computation is carried out by a network of links. In the simplest
case, a link is just a wire connecting a node of an input map to a
node of an output map. In other cases, a link is an elementary
circuit cell. Networks of links are somewhat reminiscent of look-up
tables in that they hardwire an arbitrary function of one or
several variables. Interestingly, these structures are also related
to fuzzy rules, as well as some types of artificial neural
networks. The place coding approach provides several substantial
benefits over conventional analog design: Networks of links can be
synthesized by a simple procedure whatever the function to be
computed. Place coding is tolerant to perturbations and noise in
current-mode implementations. Tolerance to noise implies that the
fundamental power dissipation limits of conventional analog
circuits can be overcome by using place coding. The place coding
approach is illustrated by three integrated circuits computing
non-linear functions of several variables. The simplest one is made
up of 80 links and achieves submicrowatt power consumption in
continuous operation. The most complex one incorporates about 1800
links for a power consumption of 6 milliwatts, and controls the
operation of an active vision system with a moving field of view.
Place Coding in Analog VLSI is primarily intended for researchers
and practicing engineers involved in analog and digital hardware
design (especially bio-inspired circuits). The book is also a
valuable reference for researchers and students in neurobiology,
neuroscience, robotics, fuzzy logic and fuzzy control.
