Selective division circuit for cryptographic applications has multiplexer outputs coupled to different groups of multiplexer outputs when division is not required and required respectively

摘要

The selective division circuit has a multiplexer (100) with twice the number of inputs (102) than the number of outputs (104) and a multiplexer control (112), connecting the outputs to a first group of inputs (102a) when no division is required and to a second group of inputs (102b) when the number division is required. An Independent claim for a processor with a system bus coupled to a selective division circuit is also included.
