  The VHD storage layout is inspired by the bit-sliced method \cite{O_Neil_1997}.   \subsection{storage layout}  In VHD, each sequence break down to fixed-length segments, each of which contains w codes( w is width of processor word). If we code our alphabet with \emph{k} bits then, the \emph{w} k-bit codes in a segment are then transposed into \emph{k} w-bit words. In Figure... there is an example to how we transpose our data.    In data genomic data sets we have five character A,C,G,T,N(unknown). If code each character we three bits, A(001), C(010), G(011), T(100), then
