If a higher-rate CAM Memory clock signal can be provided at multiples of the required packet rate, that will allow for TDM within the CAM IP and potentially reduce logic and RAM resources.

Reducing the required Packet Rate parameter can also help to reduce the logic and RAM resources of the CAMs.

Other approaches to reduce the resource utilisation of CAM tables include:
  • Reducing the size (number of entries supported)
  • Reducing the num_masks parameter value (where applicable)
