Nuvation announces availability of GEOS-10 IP Core Gigabit Ethernet over SONET OC-192

San Jose, Calif., March 11, 2002 — Continuing its leadership role in high speed networking solutions, Nuvation today announced availability of its GEOS-10 Intellectual Property (IP) core at the Embedded Systems Conference in San Francisco, CA. The newly released core multiplexes up to 10 Gigabit Ethernet channels into a single Packet over SONET (POS) stream using frame-mapped GFP (Generic Framing Procedures). GEOS-10 is targeted for OEM licensees to address the rapidly growing Gigabit Ethernet market driven by the convergence of local area networks and wide area networks.

"With the new GEOS-10 core, Nuvation can help accelerate time-to-market for our leading communications clients with a simple plug-and-play solution," said Michael Worry, CEO of Nuvation. "This is a natural progression for Nuvation, both in terms of the technology fit and in terms of the business model of providing licenseable cores and integration support services."

Ideally suited for the development of Gigabit communication and LAN/WAN networking, the GEOS-10 core supports up to OC-192 bandwidth, configurable destination port address, complies with Frame Mapped Generic Framing Procedures from ITU-T, provides GE Traffic statistics per port, and integrates with POS-PHY Level 4 or POS-PHY Level 3 cores for a variety of system solutions with different bandwidths.

Additionally, the core supports full-duplex operation. On the ingress side, the GEOS-10 features automatic generation of GFP header to packet with destination port ID, and pause information transfer to destination ports. The egress side extracts pause information from control packets and generates asserts/de-asserts "pause" signals on each GE port, and de-multiplexes traffic from the SONET side into the 10 corresponding Gigabit Ethernet ports.

The GEOS-10 is currently optimized for the Altera APEX II device architecture and interfaces with Altera POSPHY Level 4 cores through an Atlantic bus. The SOPC solution interfaces to Gigabit and SONET (OC-192) PHY chips. An AIR-bus interface is included to interface to a CPU core. The GEOS-10 core will also be available for Altera Stratix devices and Xilinx Virtex-II and Virtex-II Pro devices. For more information on target devices, please email ipcores@nuvation.com.
