The external and internal algorithmic specification of an application-speci
fic digital signal processor (ASDSP) under development, dedicated to spectr
ometric applications, is presented. The processor is intended to perform th
e correction of spectrometric data subject to errors of diversified origins
, using sophisticated digital-signal-processing algorithms. The set of algo
rithms to be implemented in the processor is proposed. Its suitability for
implementation in an application-specific integrated circuit is demonstrate
d by functional design of the corresponding processor.
