Parallel Processes in Oculomotor Control

Conference paper

Abstract

With the availability of VLSI technology to build supercomputers with a large number of interacting processors, the brain-computer analogy has found a revived interest. The RAM machine by von Neumann, [1] with a global memory for data and programs and with control by a single program counter (which holds the address of the next instruction and is updated in a regular cycle), cannot serve as a useful model for the brain. Much more interesting are parallel computers, where the architecture depends strongly on the algorithms to be performed. The ultracomputer model [2] uses a large number N of identical processors which are locally connected to a few nearest neighbor processors, e.g. in a higher dimensional cubic lattice. Such an architecture has a programming style, in which periods of independent parallel computations alternate with periods of interprocessor communication and data shuffling. For certain problems algorithms can be developed where an N-processor ultracomputer is N times faster than a RAM machine. Such ultracomputers are also structurally very different from the brain. Closest to the brain’s mode of operation is the data flow concept [3].
