WebIn order to transmit PCIe packets, which are composed of multiple bytes, a one-lane link must break down each packet into a series of bytes, and then transmit the bytes in rapid succession. The device on the receiving end must collect all of the bytes and then reassemble them into a complete packet. WebNov 13, 2012 · The Address field is simply the address to which the first data DW is written. Well, bits 31-2 of this address. Note that the two LSBs of DW 2 in the TLP are zero, so DW 2 actually reads the write address itself. Multiply 0x3f6bfc10 by four, and you get 0xfdaff040. And finally, we have one DW of data.
