Pacing of a producer, operating in a producer clock domain, may be based on at least one heuristic of a credit wire that is used to return credits to the producer. The returned credits may indicate that a consumer, operating in a consumer clock domain, has consumed data produced by the producer. The at least one heuristic may be a rate at which the credits are returned to the producer. Pacing the producer based on the rate at which the credits are returned to the producer may reduce latency of the data, flowing from the producer clock domain to the consumer clock domain, by minimizing an average number of entries in use in a First-In-First-Out (FIFO) operating in a pipeline between the producer and the consumer.
