摘要： A number of symbols are received in a first integrated circuit (IC) device, where these symbols have been transmitted by a second IC device and are received over a serial point to point link. These symbols include a non-data sequence that has been inserted into a data sequence by the second device. The symbols are loaded into a buffer. The data sequence and some of the non-data sequence is unloaded from the buffer, according to a changing unload pointer. To prevent overflow of the buffer, and in response to detecting the non-data sequence, the unload pointer is changed by more than one entry so that a non-data symbol of the non-data sequence as loaded in the buffer is skipped while unloading from the buffer. In another embodiment, to prevent underflow of the buffer, the unload pointer is stalled at an entry of the buffer that contains a non-data symbol while unloading. Other embodiments are also described and claimed.

摘要： Multiple symbol sequences that have been transmitted in parallel using the same transmit clock over a serial point to point link are received. Each symbol sequence includes an instance of a first, non-data symbol. The multiple symbol sequences are buffered and the number of times an instance of a second, non-data symbol that occurs in one of the symbol sequences is changed. A first deskew process is performed, followed by a second deskew process. The first deskew process aligns an instance of the first non-data symbol in every one of the buffered symbol sequences. The second deskew process equalizes the number of instances of the second non-data symbol that follow an instance of the first non-data symbol in every one of the symbol sequences. Other embodiments are also described and claimed.
