Abstract
Consistent with the present invention, programmable input and output buffers are provided on each port of each stage of a distributed system in order to reduce data skew and preserve data synchronization. The programmable buffers provide the ability to add delay to data paths having less skew to compensate or match the skew associated with data paths having greater skew. Accordingly, the programmable buffers can equalize data skew and preserve data synchronization at each stage in the distributed system. As a result, individual stages can be placed farther apart, thereby facilitating larger distributed systems.
