Priority Content Addressable Memory (PCAM)

摘要

A priority content addressable memory (PCAM) may store entries associated with a corresponding priority data. The PCAM may store a new entry in an available space in the memory without re-ordering the entries. Such an approach may enhance the system performance. Also, a network device may comprise multiple PCAMs for performing multiple operations in multiple cycles for a packet based on the various packet parameters. The network device may select the output of PCAMs based on the priority associated.
