An insect as a LOT of memory.
Your average house fly has about 100,000 neurons, each with
100 to 1000 synapses (connections to other neurons).
In the simplest neural network models, each synapse acts
like a multiplicative coefficient whose value is variable
(the result of a combination of genetic determination and learning).
Assuming each synapse is about 1 byte, a fly would have
about 10 to 100MB of memory.
Assuming that each synapse does a simple multiply/add
operation (which is a gross over simplification), and
given that the "cycle time" of a neuron is about 1ms
the computational power of a fly is about 10-100 million
operations per second.
So in principle, you could simulate a very simplified model
of the nervous system of a fly on a fast PC, not on an RCX.
