RLL (1,7) encoder with single state bit |
摘要 |
An apparatus for producing, from four consecutive unconstrained data bits in a bit string, a run-length-limited (RLL) encoded symbol consisting of three coded data bits. The internal state of the encoder is described by one state bit. The encoder performs RLL (1,7) encoding on a bit-by-bit basis, and can be cascaded in parallel to perform encoding on sequential, equally-sized groups of unencoded data bits. An attractive feature of the encoder is that it can be cascaded to simultaneously encode consecutive bytes of data.
