Low-latency deserializer having fine granularity and defective-lane compensation

A computer system for operating a data transmission system, the data transmission system comprising a transmitter and a receiver, the computer system comprising a memory communicatively coupled to a processor, wherein the processor is configured to implement processor operations comprising:

• controlling the transmitter to send serialized data from the transmitter through a plurality of lanes to the receiver;
• wherein the serialized data comprises multiple streams of lane-assigned data, wherein each of the multiple streams of the lane-assigned data is assigned to travel over a distinct one of the plurality of lanes;
• wherein a defective lane compensation circuit of the data transmission system is configured to perform multiple iterations of a dynamic reassignment configured to dynamically distribute the lane-assigned data among each one of a non-degraded set of the plurality of lanes during each cycle in a set of cycles;
• wherein the transmitter sends the serialized data at a first serialization ratio;
• wherein the receiver is configured to receive and load the serialized data at a second deserialization ratio;
• and
• wherein the first serialization ratio is greater than the second deserialization ratio.

A computer program product for operating a data transmission system, the data transmission system comprising a transmitter and a receiver, the computer program product comprising a computer readable program stored on a computer readable storage medium, wherein the computer readable program, when executed on a processor, causes the processor to perform a method comprising:

• controlling the transmitter to send serialized data from the transmitter through a plurality of lanes to the receiver;
• wherein defective lane compensation circuitry of the data transmission system is configured to, based on identification of at least one degraded lane among the plurality of lanes, perform rerouting operations configured to reroute data that would have been transmitted over at the least one degraded lane among a set of the plurality of lanes that have not degraded;
• wherein the transmitter sends the serialized data at a first serialization ratio;
• wherein the receiver is configured to receive and load the serialized data at a second deserialization ratio;
• and
• wherein the first serialization ratio is greater than the second deserialization ratio.
