Other Applications of CAM

By | Published: September 17, 2009
We see many in previous post, now we can see other applications of CAM. 1. MPLS switching at core and edge routers. MPLS switching involves label look up in place of an IP address look up. MPLS label consists of label value, QoS, stack flag and TTL (time to live). When a look up [...]

Working of a CAM

By | Published: September 8, 2009
Let us see how CAM works in hardware. As mentioned earlier CAM can be binary or ternary. Binary CAM cell CAM logic will simply have the storage circuitry and comparator logic to provide the match information for the searches performed. In this case a XOR gate is used to compare between the stored data and the [...]

Software and Hardware CAM

By | Published: September 5, 2009
Hardware search engines are faster than algorithmic approaches for search intensive applications. Also, the turnaround time of a hardware CAM would be highly deterministic while that of software would depend on how efficiently the search-tree balancing algorithm is implemented. However, software would results in low costs. Hybrid CAMS integrate the robustness of a hardware CAM [...]

CAM’s : Memories Faster then RAM’s

By | Published: August 27, 2009
Content Addressable Memorys (CAM’s) in their most trivial form, work in a way opposite to conventional memories. While a random access memory (RAM) returns data upon providing the address, a CAM provides address when data is supplied. So effectively a CAM is a search tool that looks for the data in question within [...]
