Transparent port aggregation in multi-chip transport protocols

Abstract:

Various implementations of a multi-chip system operable according to a predefined transport protocol are disclosed. In one embodiment, a system comprises a first IC comprising a processing element communicatively coupled with first physical ports. The system further comprises a second IC comprising second physical ports communicatively coupled with a first set of the first physical ports via first physical links, and one or more memory devices that are communicatively coupled with the second physical ports and accessible by the processing element via the first physical links. The first IC further comprises a data structure describing a first level of port aggregation to be applied across the first set. The second IC comprises a first distribution function configured to provide ordering to data communicated using the second physical ports. The first distribution function is based on the first level of port aggregation.
