This application note describes how to retrieve user-defined data from Xilinx configurationPROMs (XC18V00 and Platform Flash devices) after the same PROM has configured theFPGA. The method to add user-defined data to the configuration PROM file is also discussed.The reference design described in t ...

The exacting technological demands created byincreasing bandwidth requirements have given riseto significant advances in FPGA technology thatenable engineers to successfully incorporate highspeedI/O interfaces in their designs. One aspect ofdesign that plays an increasingly important role isthat o ...

The Virtex™-4 user access register (USR_ACCESS_VIRTEX4) is a 32-bit register thatprovides direct access to bitstream data by the FPGA fabric. It is useful for loadingPowerPC™ 405 (PPC405) processor caches and/or other data into the FPGA after the FPGAhas been configured, thus achieving ...

  The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Spec ...

This application note covers the design considerations of a system using the performance features of the LogiCORE™ IP Advanced eXtensible Interface (AXI) Interconnect core. The design focuses on high system throughput through the AXI Interconnect core with F MAX  and area optimizat ...

  Xilinx FPGAs require at least two power supplies: VCCINTfor core circuitry and VCCO for I/O interface. For the latestXilinx FPGAs, including Virtex-II Pro, Virtex-II and Spartan-3, a third auxiliary supply, VCCAUX may be needed. Inmost cases, VCCAUX can share a power supply with VCCO.The ...
