Fujitsu Laboratories Develops 56 Gbps Receiver Circuit for Communications between CPUs
Fujitsu Laboratories today announced the development of a receiver circuit capable of receiving communications at 56 Gbps. This marks the world’s fastest data communications between CPUs equipped in next-generation servers. In recent years, raising data-processing speeds in servers has meant increasing CPU performance, together with boosting the speed of data communications between chips, such as CPUs. However, one obstacle to this has been improving the performance of the circuits that correct degraded waveforms in incoming signals.
Fujitsu Laboratories has used a new “look-ahead” architecture in the circuit that compensates for quality degradation in incoming signals, parallelizing the processing and increasing the operating frequency for the circuit in order to double its speed. This technology holds the promise of increasing the performance of next-generation servers and supercomputers.
