Abstract
A hardware forwarding element is provided that includes a group of unit memories, a set of packet processing pipelines, and an error signal fabric. Each packet processing pipeline includes several of match action stages. Each match action stage includes a set of match action tables stored in a set of unit memories. Each unit memory is configured to detect an error in the unit memory and generate an error output when an error is detected in the memory unit. The error signal fabric, for each match action stage, combines error outputs of the unit memories storing match tables into a first bit in the error signal fabric. The error signal fabric, for each match action stage, combines error outputs of the unit memories storing action tables into a second bit in the error signal fabric.
