Ethernet MAC Tri-Mode 10/100/1000

Ethernet MAC Tri-Mode 10/100/1000

The VCores Ethernet GMAC IP empowers hosts to transmit data using the Gigabit Ethernet protocol (IEEE 802.3) across speeds of 10M, 100M, and 1G. It comprises three primary layers: the Gigabit Ethernet Media Access Controller, the MAC Transaction Layer, and the MAC DMA Controller. The MAC Transaction Layer offers exceptional configurability, ensuring optimal performance and supporting a wide array of implementations tailored to end-system applications. Additionally, it provides extensive support for various application interfaces, facilitating seamless integration into SoCs. Leveraging silicon-proven technology and designed for straightforward integration into ASICs and FPGAs, the VCores GMAC IP boasts a user-friendly application interface, enabling designers to easily align functional and implementation goals with design requirements. Rigorously verified using cutting-edge methodologies, including RTL design, verification, hardware verification and interoperability tests, this IP effectively mitigates risks.
