Spartan-3AN 器件帶有可以用于儲存配置數據的片上Flash 存儲器。如果在您的設計中Flash 存儲器沒有與外部相連,那么Flash 存儲器無法從I/O 引腳讀取數據。由于Flash 存儲器在FPGA 內部,因此配置過程中Spartan-3AN 器件比特流處于隱藏狀態。這一配置成了設計安全的起點,因為無法直接從Flash 存儲器拷貝設計。

This application note provides a detailed description of the Spartan™-3 configurationarchitecture. It explains the composition of the bitstream file and how this bitstream isinterpreted by the configuration logic to program the part. Additionally, a methodology ispresented that will guide the user through the readback process. This information can be usedfor partial reconfiguration or partial readback.

This application note shows how to achieve low-cost, efficient serial configuration for Spartan FPGA designs. The approachrecommended here takes advantage of unused resources in a design, thereby reducing the cost, part count, memory size,and board space associated with the serial configuration circuitry. As a result, neither processor nor PROM needs to be fullydedicated to performing Spartan configuration.In particular, information is provided on how the idle processing time of an on-board controller can be used to loadconfiguration data from an off-board source. As a result, it is possible to upgrade a Spartan design in the field by sending thebitstream over a network.

Consumer display applications commonly use high-speed LVDS interfaces to transfer videodata. Spread-spectrum clocking can be used to address electromagnetic compatibility (EMC)issues within these consumer devices. This application note uses Spartan®-6 FPGAs togenerate spread-spectrum clocks using the DCM_CLKGEN primitive.

The introduction of Spartan-3™ devices has createdmultiple changes in the evolution of embedded controldesigns and pushed processing capabilities to the “almostfreestage.” With these new FPGAs falling under $20, involume, with over 1 million system gates, and under $5for 100K gate-level units, any design with programmablelogic has a readily available 8- or 16-bit processor costingless than 75 cents and 32-bit processor for less than $1.50.

針對嵌入式機器視覺系統向獨立化、智能化發展的要求,介紹了一種嵌入式視覺系統--智能相機。基于對智能相機體系結構、組成模塊和圖像采集、傳輸和處理技術的分析,對國內外的幾款智能相機進行比較。綜合技術發展現狀,提出基于FPGA+DSP模式的硬件平臺,并提出智能相機的發展方向。分析結果表明,該系統設計可以實現脫離PC運行,完成圖像獲取與分析,并作出相應輸出。 Abstract: This paper introduced an embedded vision system-intelligent camera ,which was for embedded machine vision systems to an independent and intelligent development requirements. Intelligent camera architecture, component modules and image acquisition, transmission and processing technology were analyzed. After comparing integrated technology development of several intelligent cameras at home and abroad, the paper proposed the hardware platform based on FPGA+DSP models and made clear direction of development of intelligent cameras. On the analysis of the design, the results indicate that the system can run from the PC independently to complete the image acquisition and analysis and give a corresponding output.
