IMPLEMENTATION OF FUNCTIONAL TRANSFORMATION IN THE PROGRAMMABLE LOGIC CHIPS

Functional transformation, that is, the formation of the code, which numerical equivalent is a defined function of the input code numerical equivalent, is a widespread operation in the measurement, control and similar systems. The implementation of such transformations in universal calculators (e. g. microprocessors) often does not meet the requirements of consumers in terms of performance or energy effectiveness. A review of the functional transformation methods is presented: tabular approximation, polynomial approximation, calculations according Volder method. The implementations into program logic microchips using different variants of spatial and temporal distribution of calculations are considered. It is shown that performance in the range up to 107 transformations per second with moderate costs is achievable.
