Instantiations
- i_pack_shell: pack_shell
- i_deinterleave: ad_perfect_shuffle
Description
- Data at the output of the routing network is interleaved. The upack
- core is supposed to produce deinterleaved data. This just rearrange the
- bits in the data vector and does not consume any FPGA resources.
