<p>A system for encoding consecutive parallel bytes of source data into an RLL (1,7) output symbol string and decoding an input RLL (1,7) symbol string to produce an output sequence of parallel bytes of data. The system accepts an input sequence of parallel data bytes occurring at a byte rate and provides, in response, the output RLL symbol string at a symbol string rate which is twelve times the byte rate. Similarly, the output byte sequence has a byte rate which is 1/12 of the input RLL symbol string rate. The system performs RLL encoding and decoding at the byte rate, thus eliminating the odd 2/3 f<Sub>c</Sub> source clock required in systems performing RLL coding and decoding functions on a bit-by-bit basis.</p> |
