SYSTÈME INTÉGRÉ, UNITÉ DE COMMUNICATION ET PROCÉDÉ DE MISE EN UVRE D'UN CALCUL EXPONENTIEL

摘要

An embedded system (200) is described. The embedded system (200) comprises: a processing circuit (202) comprising at least one processor configured to support an exponential computation; and a plurality of look-up tables, LUTs (420), where the LUTs are of a size less than 2^N and contain a plurality of exponential values. The processing circuit (202) is configured to: receive the input data; parse the input data into a plurality of subsets of data; extract respective exponential values from the plurality of LUTs associated with the respective data subset; and multiply the plurality (m) of extracted exponential values to produce an exponential computation of the N-bit input data (440, 540).
