Abstract
A data shuffler apparatus for shuffling input bits includes a plurality of bit shufflers each inputting corresponding two bits xand xof the input bits and outputting a vector {x', x′} such that a number of 1's at bit x′ over time is within ∀1 of a number of 1's at bit x′. At least two 4-bit vector shufflers input the vectors {x′, x′}, and output 4-bit vectors, each 4-bit vector corresponding to a combination of corresponding two vectors {x′, x′} produced by the bit shufflers, such that the 4-bit vector shufflers operate on the vectors {x′, x′} in the same manner as the bit shufflers operate on the bits xand x. The current state of the bit shufflers is updated based on a next state of the 4-bit vector shufflers.
