Deskew apparatus and method for peripheral component interconnect express |
摘要 |
Disclosed herein are a deskew apparatus and method for Peripheral Component Interconnect (PCI) Express for compensating for a skew. The deskew apparatus includes a lane data input unit, a lane data alignment unit, and a lane data detection unit. The lane data input unit receives 18-bit data from each of lanes of the PCI Express. The lane data alignment unit aligns the 18-bit data using a COM symbol. The lane data detection unit detects a change in a state of alignment of the 18-bit data attributable to deletion or addition of an SKP symbol when the 18-bit data is aligned, and to perform synchronization between the lanes. |

1. A deskew apparatus for Peripheral Component Interconnect (PCI) Express for compensating for a skew, the deskew apparatus comprising:
a lane data input unit configured to receive 18-bit data from each of lanes of the PCI Express; a lane data alignment unit configured to align the 18-bit data using a COM symbol; and a lane data detection unit configured to detect a change in a state of alignment of the 18-bit data attributable to deletion or addition of an SKP symbol when the 18-bit data is aligned, instead of by detecting the COM symbol, and to perform synchronization between the lanes. |
