IDT joins Texas in crossbar low-voltage logic
IDT and Texas Instruments have entered a co-operative agreement to become alternate supply sources of 3.3V crossbar low-voltage technology (CBTLV) bus switch devices.
IP coprocessors provide flexible search width
IDT has released its first commercially available Internet protocol coprocessor product portfolio that enables up to OC-768 wire speed to support ever-increasing packet processing requirements.
The new architecture supports a wider interface, making it the first NSE architecture truly optimised for creating future products that efficiently support IPv6.
IDT has also implemented an error correction code feature never before implemented in an NSE that addresses potential soft errors, ensuring data integrity and compliance with stringent service level agreements.
"With IPv6 on the horizon, new services such as VoIP, and the proliferation of CPE devices, access control lists become more complex, making the classification function more important than ever", said Allan Armstrong, director of communications semiconductors at analyst firm RHK.

Eight-port programmable voice access solution
Intersil and IDT have developed a new space- and cost-saving high-density eight-port (HD8) voice access solution for enterprise markets.
"NSEs are an excellent tool for enterprise switch and carrier router developers creating highly differentiated boxes, as they accelerate a key function without compromising a system vendor's intellectual property".
The newest IDT architecture offers several innovative features that make it an ideal solution for 10Gbit/s applications.
The ECC feature, the first of its kind in an NSE architecture, improves data integrity and addresses soft errors, which are caused when neutrons in the earth's atmosphere collide with electronics systems.
These soft errors can cause a system to malfunction or act unpredictably, which is unacceptable in high-reliability networking equipment.
By automatically checking and correcting impacted code before it can affect functionality, devices based on this architecture will help to maintain consistent system operation.
The quad simultaneous multiple-database lookup feature enables industry-leading performance of up to one billion searches per second by supporting four simultaneous lookups in one cycle with an unprecedented core search rate of 250 million searches per second.
The new architecture also leads the industry in supporting an 80bit base search width that efficiently supports IPv6 by offering a 320bit search width to accommodate a 296bit wide IPv6 quintuple lookup, thereby optimising the database size for those operations.
The first NSE products based on the fourth-generation IDT architecture will be available in the first half of 2005.
Initial products are expected to include a high-speed transceiver logic (HSTL) interface to ASICs and FPGAs.
