Abstract

The CHASM is a "fixed plus variable" computer system composed of a specialized marcomodular processor coupled to a LINC. The CHASM is designed to carry out the analysis of a Markov process model for the time patterns of spike discharges of neurons. The fixed portion of the CHASM computes certain probabilities associated with the Markov process model. The LINC provides input and output for the fixed portion and controls the execution of the calculations. The bulk of the calculations is efficiently carried out by the fixed portion. The more irregular operations, which occur less frequently, are carried out by the LINC.
