One of the unique aspects of AXIe is the local bus. As reported back in the March 2013 AXIe Newsletter, the local bus is a unique bus structure that brings a lot of hidden benefits. It is a segmented bus that connects only between adjacent slots. A left to right flow allows very high speed streaming and independent use of each between vendors and applications.
The AXIe local bus topology delivers unique capabilities of performance and flexibility, while retaining interoperability between vendors. The previously demonstrated speed of 40GB/s was already best in class performance. The ability to achieve 80GB/s and effectively double the data-rate, shows that AXIe local bus speeds are able to scale with semiconductor performance, as predicted.
