    • This invention relates to a coding circuit for generating a swap tolerant code. The coding circuit comprises a first and second input (540, 541 ), an odd parity pair detector (535), a memory (533), and an output circuit (536, 537, 551; 736, 737, 751 ). Each of the first and second inputs (540, 541 ) receive a stream of serial data. The odd parity pair detector (535) outputs an odd parity pair signal if the bits received at said first and second inputs (540, 541 ) have different logical values and therefore constitute an odd parity pair. The memory (533) stores information on a previous odd parity pair. The output circuit outputs the previous odd parity pair, if said first input (540) provides a logical 1 and said second input (541 ) provides a logical 0. The output circuit outputs the inverted previous odd parity pair, if said first input (540) provides a logical 0 and said second input (541 ) provides a logical 1. The invention further provides a corresponding decoding circuit, and coding and decoding methods. Further the invention relates to a coding circuit for inversion tolerant coding, a corresponding decoding circuit and coding and decoding methods.
    • 本发明涉及一种用于生成交换容错码的编码电路。 编码电路包括第一和第二输入(540,541),奇校验对检测器(535),存储器(533)和输出电路(536,537,551; 736,737,751)。 第一和第二输入(540,541)中的每一个接收串行数据流。 如果在所述第一和第二输入(540,541)处接收的比特具有不同的逻辑值并且因此构成奇偶校验对,则奇校验对检测器(535)输出奇校验对信号。 存储器(533)存储关于先前的奇校验对的信息。 如果所述第一输入(540)提供逻辑1,并且所述第二输入(541)提供逻辑0,则输出电路输出先前的奇偶校验对。如果所述第一输入(540) )提供逻辑0,并且所述第二输入(541)提供逻辑1.本发明还提供相应的解码电路,以及编码和解码方法。 此外,本发明涉及一种用于反转容限编码的编码电路,一种对应的解码电路和编码和解码方法。
