Avoid reduced effective bandwidth on transmission lines in the presence of clock domain differences

Abstract

An apparatus and method for efficiently routing power signals across a semiconductor die. In various implementations, a computing system includes transmitters sending data signals to receivers that support using a prefix to provide clock recovery and alignment of the input bit stream that arrives at the receivers. Based on when a decoder of a receiver receives the prefixes, the decoder determines which clock cycles to skip writing data into a buffer of data processing circuitry. Therefore, the decoder prevents overflow of this buffer when the rate of insertion is greater than the rate of removal for this buffer. In contrast, the transmitter continues to send data during each clock cycle, and accordingly, avoids reducing the effective bandwidth on transmission lines in the presence of clock domain differences between transmitter and receiver.
