eTCAM (Embedded Ternary Content Addressable Memory IP

Overview

TCAM can search for data that matches the input in one cycle from all the information stored in the memory.If there are multiple matching data, it is possible to find all of them.By adding a priority encoder (RTL), it is possible to select one from multiple matching data.

Key Features

  • One cycle operation latency (without priority encoder)
  • Valid Bit per entry to reduce power
  • Valid Bit reset in one cycle support
  • Mask input option for bit-write and masked search key
  • Additional power emulation library support
  • BIST support with redundancy

Benefits

  • Small area:
    • By optimizing the peripheral circuit of memory, particularly small area is realized.
  • Low power:
    • Optimized low leakage design, valid bit control and search mask will make low power performance achievable. What s more, providing a design environment that allows customer to confirm the power saving feature according to the actual usage conditions.
  • IDM-oriented design quality:
    • Many product proven.
