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.

XAPP520將符合2.5V和3.3V I/O標準的7系列FPGA高性能I/O Bank進行連接 The I/Os in Xilinx® 7 series FPGAs are classified as either high range (HR) or high performance (HP) banks. HR I/O banks can be operated from 1.2V to 3.3V, whereas HP I/O banks are optimized for operation between 1.2V and 1.8V. In circumstances that require an HP 1.8V I/O bank to interface with 2.5V or 3.3V logic, a range of options can be deployed. This application note describes methodologies for interfacing 7 series HP I/O banks with 2.5V and 3.3V systems

摘要: 串行傳輸技術具有更高的傳輸速率和更低的設計成本, 已成為業界首選, 被廣泛應用于高速通信領域。提出了一種新的高速串行傳輸接口的設計方案, 改進了Aurora 協議數據幀格式定義的弊端, 并采用高速串行收發器Rocket I/O, 實現數據率為2.5 Gbps的高速串行傳輸。關鍵詞: 高速串行傳輸; Rocket I/O; Aurora 協議 為促使FPGA 芯片與串行傳輸技術更好地結合以滿足市場需求, Xilinx 公司適時推出了內嵌高速串行收發器RocketI/O 的Virtex II Pro 系列FPGA 和可升級的小型鏈路層協議———Aurora 協議。Rocket I/O支持從622 Mbps 至3.125 Gbps的全雙工傳輸速率, 還具有8 B/10 B 編解碼、時鐘生成及恢復等功能, 可以理想地適用于芯片之間或背板的高速串行數據傳輸。Aurora 協議是為專有上層協議或行業標準的上層協議提供透明接口的第一款串行互連協議, 可用于高速線性通路之間的點到點串行數據傳輸, 同時其可擴展的帶寬, 為系統設計人員提供了所需要的靈活性[4]。但該協議幀格式的定義存在弊端,會導致系統資源的浪費。本文提出的設計方案可以改進Aurora 協議的固有缺陷,提高系統性能, 實現數據率為2.5 Gbps 的高速串行傳輸, 具有良好的可行性和廣闊的應用前景。

在游客游跡跟蹤與追溯系統中,產生大量不確定數據,有效的Top-K查詢處理是不確定性數據管理中一項重要技術。研究了運用Top-K檢索不確定數據的問題,定義了不確定數據流元組的查詢語義,提出了一種在記錄向量的基礎上的不確定數據查詢算法,并利用實例演示了查詢的過程。該算法按照元組的得分值進行降序排列,概率值最高的前k個元組集合就是Top-K的查詢結果,實驗結果表明,本文的算法更具高效性和實用性。
