Overview

TCAM has traditionally been adopted in network hub equipment and is often used for high-speed IP address searches. RAM, which is a typical memory, specifies an address and outputs the data, but TCAM inputs data and outputs the matching address.

KEY FEATURES OF TCAM

  • TCAM searches for data that matches the input value in one cycle from all information stored in the memory.
  • If there are multiple matching data, find all of them Also, by adding a priority encoder, it is possible to select one from multiple matching data.
  • The search key input (Search In) hascapability with a bitwise mask function to support various searches.

Key features

  • Designed as small-capacity TCAM hard macro: RTL Wrapper provided by Renesas supports Entry Address/Bit width beyond the hardware macro support range.
  • Search results for each address are output directly from the hard macro: Sorting of search results is realized by adding a priority encoder soft macro
  • Efficient search with Valid Bit control function: Valid Bit that indicates whether the search target is valid or invalid provided for each address omits the search for areas in which data is not stored. Power consumption is reduced because search operations are not performed with invalid addresses.
  • Improved user convenience with Valid Bit Reset function: Function to initialize Valid Bit in one cycle and set all addresses to invalid for Simplifies startup sequence at power-on.
  • Change search key length by Search Mask function: In cases where the search keyword is long, the length of the search key can be changed by partially masking it. It can be specified for each bit.
  • Pre-Search function (supported N7 only) saves power: Power consumption is reduced by searching a part of the key first and then searching the remaining part only if it matches.

Implementing Ultra Low Latency Data Center Services with Programmable Logic

Data centers require many low-level network services to implement high-level applications. Key-Value Store (KVS) is a critical service that associates values with keys and allows machines to share these associations over a network. Most existing KVS systems run in software and scale out by running parallel processes on multiple microprocessor cores to increase throughput.

Generating High Speed CSI2 Video by an FPGA

In this article, we show how fast video streams conforming to MIPI CSI2 rev2.0 over MIPI DPHY rev1.2 can be generated, using VLSI Plus’ SVTPlus-CSI2-F IP core, with simple off-FPGA analog front-end. The high bit rates can be achieved with a relatively slow FPGA clock frequency, trading off FPGA resources for simple timing closure.
