Network traffic search accelerator

IDT has added the IDT 75S10000B series to its family of application-optimised search accelerator solutions. The series offers high performance, low power and cost effective packet header processing solutions for enhanced table support up to 40Mbit in enterprise-, metro- and carrier-class switches and routers. The new devices extend search performance to 1.2billion searches per second. The new series also introduces current surge control, an advanced power management technique that allows the user to minimise voltage drop on the core power supply during a search, enabling improved signal integrity within the customer’s application.
The new devices can be used to combat complex network challenges such as quad-play-ready networking applications. The IDT 75S10000B search accelerator series improves security and access control, and supports broader address spaces, while maintaining high-availability bandwidth at line rates of 40Gbit/s and beyond. Being pin and software compatible with the existing family members, the IDT 75S10000B series allows users of the 75S10000A search accelerator series in their production designs to adopt the new series of devices and thereby preserve their hardware and software investments. The 75S10000B series also introduces flexible results in management, allowing customers to optimise their packet processing solutions around their search performance needs. This can deliver up to a 20% reduction in interface pin count to the search complex, while providing a 20% increase in performance and 100% increase in density.

The 75S10000B devices implement enhanced error detection and correction (ECC) and ensure data integrity. IDT implements dedicated ECC and parity bits that preserve a true 80-bit data interface. The devices also offer advanced power saving features, such as dynamic database management and intelligent pipelined search. These techniques can be used in tandem to selectively reduce the number of entries being searched during table look-ups, reducing power consumption by up to 75%.
