Xilinx Ethernet AVB Endpoint LogiCORE IP
Industry Demands • Guaranteed transportation of streaming audio and video on Ethernet-based networks • Scalable open standards • Flexibility to meet emerging specification changes
The Xilinx Solution • Time synchronization (IEEE 802.1 AS) and traffic shaping (IEEE 802.1 Qav) to guarantee high quality of service • Paramaterizable core, delivered through CORE Generator™ software, operating at 100 Mbps or 1Gbps based upon standard Ethernet
• Fully flexible, highly integrated system design for seamless adaptability and multiple use models
The Xilinx Ethernet Audio Video Bridging (AVB) Endpoint LogiCORE™ IP core, designed to emerging IEEE 802.1 standard from the AVB Task Group, delivers a flexible solution to enhance standard Ethernet MACs. The core provides prioritized channels through an existing MAC designed to supply a reliable, time synchronized, low latency, and high Quality of Service (QoS) solution for real-time audio or video data.
Scalable FPGA-based Solution for Multimedia-enhanced Markets Offering portability to the high performance Xilinx Virtex®-6 FPGAs and the low cost Extended Spartan®-6 family FPGAs, the core is ideal for streaming audio and video applications for broadcast, automotive, consumer and industrial markets. This FPGAbased solution allows designers to implement an unlimited number of channels based upon available resources. The Ethernet AVB Endpoint adapts seamlessly to the Xilinx standard soft or integrated Tri-mode Ethernet MAC at 100 Mbps or 1 Gbps.
Optimal Bandwidth Preservation Supporting data transfer for AV and legacy traffic, the core enables arbitration between data and implements bandwidth policing. This allows the user to reserve 75% of the bandwidth for AV traffic and 25% for legacy traffic thereby guaranteeing reliable data throughput.
High-Speed Processing of Timing Packets The Ethernet AVB Endpoint core and on-board 32-bit MicroBlaze™ soft processor eliminates the need for an external host processor, allowing ultra-fast processing of timing packets. The Xilinx FPGA fabric assists in hardware time-stamping of packets to eliminate operating system delays.
