Expanding on its neural network computer simulation announcement (CI No 838), Fujitsu Ltd says that the putative machine would have an infinite number of signal transmission routes between the node processing elements that will make up the computer: the simulator has 100,000 nodes – each node a processing element with its own memory – networked with a million paths between neurons, an average of 10 connections per node, although Fujitsu says that each neuron can see 50 signal transmission routes compared with the mere four supported by the Inmos Transputer; Fujitsu’s next target is to perfect a super-heat-resistant neuro-chip node microprocessor, likely to take two to three years, after which it hopes to use it to build a neural computer made up of millions of neurons, which it believes could emulate the functioning of a vertebrate or even a human brain.
