Abstract
We examine three correlation time-of-flight (CTOF) techniques that are most promising for neutron, molecular and ion beam spectroscopy. The techniques use pseudorandom binary sequences as input modulations. In particular we study the degree of parallelism in the identification procedures which yield univariable or multivariable response functions. The time-complexity of the algorithms involved is discussed as a function of the number of parallel processors available. The indirect character of CTOF techniques and the experiment control and assessment make real-time evaluation essential. Therefore the design of parallel processor structures capable of performing parallel algorithms in real-time is presented for the three CTOF methods.
