With the exploding number of “things” connected to the internet and the real-time feedback requirements of these devices, demands for network systems with much higher speeds are growing bigger year after year. As the industry migrates to 100Gb traffic, high power consumption of traditional search engine solutions becomes a huge problem for data center networks. Renesas offers a low power search solution for higher packet forwarding that grows with your network.

The Renesas Exact Match reference design includes a proprietary search algorithm, LLDRAM-III control IP on an FPGA host controller, and is accompanied by a suite of development tools.

Exact Match Reference Design Key Features

  • Lookup over one million rules of packet headers for a 100Gb network system in around 2 watts, which means the quantity of required memory devices is reduced to 1/15th and memory power consumption is cut by 60%.*
  • Scale with future network protocols with flexible configuration of the search key length of up to 575 bits.
  • Reduce the development cycle time of network systems by providing an all-in-one development platform with an on-board Xilinx FPGA and LLDRAM-III

*If MAC address lookup at 150 million search per second
