SAN JOSE, Calif. -- inSilicon Corporation (Nasdaq:INSN) -- a leading provider of connectivity semiconductor intellectual property (IP), today announced the latest addition to their Gigabit Ethernet intellectual property product line, the Gigabit Ethernet MAC Subsystem (GMAC Subsystem). At 1-Gbps operations, the GMAC Subsystem serves the higher bandwidth data transfer requirements of high-speed, embedded communication system-on-chip (SOC) applications, and is backward compatible with the Ethernet standard for 10- and 100-Mbps operation. Built using inSilicon's silicon-proven Gigabit Ethernet MAC (GMAC) intellectual property technology, the GMAC Subsystem supports 10/100-Mbps and 1-Gbps data rates, special hardware filtering, VLAN, power management, and remote monitoring. GMAC also supports jumbo packets and control frames in Half- and Full-Duplex modes. This product is fully compliant with the IEEE 802.3x standard and provides the interface to IEEE 802.3z-specified (GMII) copper wire PHYs. "Many of our customers require more than a GMAC port, such as additional frame buffers and a DMA engine," said Fawzi Masri, product marketing manager of inSilicon Corporation. "With our expertise in reusable IP and this feature-rich product, we are providing more value to our SOC customers by reducing their design effort and shortening design time with an integrated and tested Gigabit Ethernet subsystem solution."
