Permutation instruction

WebIn particular, we propose fast bit gather (or parallel extract), bit scatter (or parallel deposit) and bit permutation instructions (including group, butterfly and inverse butterfly). We show that all these instructions can be implemented efficiently using both the fast butterfly and inverse butterfly network datapaths. WebThe instruction coding and the low-level implementation for the instructions are quite simple. An algorithm is also given to derive an instruction sequence for any arbitrary permutation.
