Abstract:
A data planarizer comprising:a plurality of data input terminals for receiving n-bit data words;a plurality of data output terminals for outputting planarized m-bit data words; anda first storage bank having an input terminal set coupled to said plurality of data input terminals, an output terminal set coupled to said plurality of data output terminals, and a bit-depth less than m, for receiving and accumulating said n-bit data words, and for outputting said accumulated data as first portions of said m-bit planarized data words, andwherein said first storage bank comprises a bi-directional shift register, adapted to shift said n-bit data words into said first storage bank in a first direction and to shift said first portions of said m-bit data words out of said first storage bank in a different direction.
