Virtex-4 devices are user-programmable gate arrays with various configurable elements and embedded cores optimized for high-density and high-performance system designs. Virtex-4 devices implement the following functionality:
• Cascadable embedded XtremeDSP slices with 18-bit x 18-bit dedicated multipliers, integrated Adder, and 48-bit accumulator.
• Integrated high-speed serial transceivers enable data rates up to 6.5 Gb/s per channel.
• Embedded IBM PowerPC 405 Processor RISC CPU (up to 450 MHz) with the auxiliary processor unit interface
• 10/100/1000 Ethernet media-access control (EMAC) cores.
Tri-Mode Ethernet Media Access Controller
• Implements SGMII through RocketIO MGT to external PHY device • Supports multiple PHY (MII, GMII, etc.) interfaces through an I/O resource • Receive and transmit statistics available through separate interfaces • Separate host and client interfaces • Support for jumbo frames • Flexible, user-configurable host interface
