Abstract: Devices, systems, methods, and processes for transmitting and receiving one or more data packets are described herein. A device may face an internal non-deterministic delay in processing causing a gap or an interruption during transmission of the data packet. During the gap, the device can transmit one or more Intra-Packet Idle (IPI) words between the transmission of the data packet. The IPI words can be ignored or discarded by a receiver. The device may transmit the data packet into multiple parts by transmitting the IPI words between the parts. The receiver can receive the parts of the data packet and the IPI words and retrieve the data packet based on the parts of the data packet. The device may set a configurable threshold value indicative of a maximum number of the IPI words that can be transmitted during the gap of the interruption, such that the receiver can efficiently identify and discard a runt packet. The device does not require a buffer to fetch and store the data packet prior to the transmission, thereby eliminating a latency caused by the buffer.

Abstract: A method for receiving packet data at a communication channel and transmitting the packet data over serial links of the communication channel. The packet data is sliced into n-bit data portions which are concatenated with a header prior to transmitting an n-bit portion across one of the serial links of the communication channel. The header may include an invert bit to alter the majority sign of an n-bit portion. Other aspects of the present invention are also described herein.

Abstract: A channel synchronization method in which local serializers serially transmits first n-bit codes, respectively, to remote deserializers, respectively. Also local deserializers serially receive first n-bit codes, respectively, from remote serializers, respectively. One of the first n-bit codes transmitted to one of the remote serializers indicates one of the local deserializers is not link aligned.

Abstract: In one embodiment, a method includes receiving an input signal at a local data lane comprising a dynamic entry shift register, the input signal comprising a marker also received at a remote data lane, identifying receipt of the marker in the local data lane, starting a timer and notifying the remote data lane that the marker was found, receiving a marker found status from the remote data lane and saving a value of the timer, calculating a compensated delay for the remote data lane based on the timer value and a number of pipeline stages for the remote data lane, and setting an entry point to the dynamic entry shift register based on the compensated delay to deskew data between the local data lane and the remote data lane.

Abstract: A method for performing packet reorder processing is disclosed. The method comprises receiving, at a packet receive buffer, a data packet, the packet receive buffer comprising a plurality of N-sized pages. The method also comprises storing the received data packet across a plurality of pages of the packet receive buffer. The method further comprises writing, at storage of each of the plurality of pages, a pointer to a next page in which a subsequent portion of the data packet is stored. The method also comprises transmitting the pointer to a ring buffer. The method further comprises calculating an offset to the ring based on a sequence number of the corresponding packet, and storing the pointer to a first page in the calculate offset of the ring buffer.
