A lot of systems today have dedicated processors that do one function in a system. Sometimes the processors may be from different vendors and have different characteristics, for example different bus widths. This device allows those different processors to communicate. |
Every fifth clock cycle you have a deterministic message that is sent to the losing port. You monitor the software and it tells you where the issue happened. Then you go directly to that spot and fix it. Previously this was only available in asynchronous memories. When you have a lot of clock skews and rates it becomes a bit more challenging to find collisions. |
The 72-bit bus width is key because it allows them to interconnect with the new processors in the market that are going toward 64-bit interfaces. |
