The UltraScale architecture is the industr y's f irst application of leading-edge ASIC architectural enhancements in an All Programmable architecture that scales from 20 nm planar through 16 nm FinFET technologies and beyond, in addition to scaling from monolithic through 3D ICs. Through analytical co-optimization with the X ilinx V ivado® Design Suite, the UltraScale architecture provides massive routing capacity while intelligently resolving typical bottlenecks in ways never before possible. This design synergy achieves greater than 90% utilization with no performance degradation. Some of the UltraScale architecture breakthroughs include: • Strategic placement (virtually anywhere on the die) of ASIC-like system clocks, reducing clock skew by up to 50% • Latency-producing pipelining is virtually unnecessary in systems with massively parallel bus architecture, increasing system speed and capability • Potential timing-closure problems and interconnect bottlenecks are eliminated, even in systems requiring 90% or more resource utilization • 3D IC integration makes it possible to build larger devices one process generation ahead of the current industr y standard • Greatly increased system performance, including multi-gigabit serial transceivers, I/O, and memor y bandwidth is available within even smaller system power budgets • Greatly enhanced DSP and packet handling The Xilinx UltraScale architecture opens up whole new dimensions for designers of ultra-high-capacity solutions.

Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.

Abstract: This application note discusses the development and deployment of 3G cellular femtocell base stations. The technicalchallenges for last-mile residential connectivity and adding system capacity in dense urban environments are discussed, with 3Gfemtocell base stations as a cost-effective solution. Maxim's 3GPP TS25.104-compliant transceiver solution is presented along withcomplete radio reference designs such as RD2550. For more information on the RD2550, see reference design 5364, "FemtocellRadio Reference Designs Using the MAX2550–MAX2553 Transceivers."

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 optimizations in certain portions of the design. The design uses five AXI video direct memory access (VDMA) engines to simultaneously move 10 streams (five transmit video streams and five receive video streams), each in 1920 x 1080p format, 60 Hz refresh rate, and up to 32 data bits per pixel. Each VDMA is driven from a video test pattern generator (TPG) with a video timing controller (VTC) block to set up the necessary video timing signals. Data read by each AXI VDMA is sent to a common on-screen display (OSD) core capable of multiplexing or overlaying multiple video streams to a single output video stream. The output of the OSD core drives the DVI video display interface on the board. Performance monitor blocks are added to capture performance data. All 10 video streams moved by the AXI VDMA blocks are buffered through a shared DDR3 SDRAM memory and are controlled by a MicroBlaze™ processor. The reference system is targeted for the Virtex-6 XC6VLX240TFF1156-1 FPGA on the Xilinx® ML605 Rev D evaluation board
