FPGA based Ternary Content Addressable Memory using SRAM
نویسندگان
چکیده
Ternary content addressable memory, TCAM is a semiconductor memory device, operates for determining a match between received search data and stored data in TCAM bitcells. TCAM performs high speed lookup operations, but when compared to RAM technology the conventional TCAM circuitry suffers from certain limitations such as low access time, low storage capacity, circuit complexity and much high cost. So, here TCAM cells are combined with SRAM to emulate itsfunctionality. A8X4 design has been implemented using vertical partitioning and hybrid partitioning of conventional TCAM table in Xillinx Virtex-2 FPGA. After analysis, it is finding that the results of VP-SRAM based TCAM are better in terms of area and maximum combinational path delay.

Ternary Content Addressable memory is a type of memory that allows the memory to be searched by content rather than by address. It performs high speed lookup operations within a single clock cycle. But when compared to RAM technology the conventional TCAM circuitry has certain limitations such as low access time, low storage capacity, circuit complexity and high cost. So we can use the benefits...

Ternary content addressable memories (TCAMs) perform high-speed search operation in a deterministic time. However, when compared with static random access memories (SRAMs), TCAMs suffer from certain limitations such as lowstorage density, relatively slow access time, low scalability, complex circuitry, and higher cost. One fundamental question is that can we utilize SRAM to combine it with addi...

Ternary content addressable memories (TCAMs) perform high-speed lookup operation but when compared with static random access memories (SRAMs), TCAMs have certain limitations such as low storage density, relatively slow access time, low scalability, complex circuitry, and are very expensive. Thus, can we use the benefits of SRAM by configuring it (with additional logic) to enable it to behave li...

Content addressable memory (CAM) is a type of solid-state memory in which data is provided as input and an operation is performed to returns the address as output. Unlike other memories (SRAM, DRAM), it performs the search operation in parallel on complete location at once, offered significant reduction in searching time. A ternary content addressable memory (TCAM) is a specialized CAM design f...
