亲爱的用户,您好!
我有一个带有Spartan 3E 1600版FPGA的Xilinx Microblaze开发套件。 我想要做的是在FPGA中实现Microblaze,并且必须能够重新配置部分FPGA,以便为Microblaze实现不同的periferal。 我已经读过Spartan3 FPGA支持部分重配置,但我不知道它是否支持动态重配置,而Microblaze仍在使用中。 有帮助吗? 提前致谢 缺口, 斯巴达,希腊 以上来自于谷歌翻译 以下为原文 Hello dear users I have a Xilinx Microblaze Development Kit with Spartan 3E 1600 edition FPGA. What i want to do, is to implement the Microblaze in the FPGA, and have to ability to reconfigure part of the FPGA so as to implement diferent periferals for the Microblaze. I have read that Spartan3 FPGAs support partial reconfiguration, but i don't know if it support dynamic reconfiguration, while Microblaze is still in use. Any help ? Thanks in advance Nick, Sparta,Greece |

最简洁的答案是不。
更长的答案是: - 至少有一篇我见过的论文涉及这个范围的一部分:http://www.cmpe.boun.edu.tr/~yurdakul/papers/BayarHiPEAC08.pdf(Spartan上的动态部分自我重新配置 - III FPGA通过并行配置访问端口(PCAP)) - 当前的ISE PR软件(9.2.04PR11)不支持Spartan-3。 - Spartan设备比Virtex-4等设备有更多限制 更多信息在这里: http://www.xilinx.com/support/answers/18416.htm(6.3i部分重配置 - Spartan-3 / -3E设备是否支持部分重配置?) http://forums.xilinx.com/xlnx/board/message?board.id=Virtex&thread.id=2446(动态可重新配置) http://forums.xilinx.com/xlnx/board/message?board.id=GenDis&message.id=991(是否有任何virtex设备只允许重新配置逻辑块,而不是整列?) http://www.xilinx.com/support/answers/25018.htm(部分重新配置 - PlanAhead Flow FAQ /了解早期访问部分PlanAhead计划的问题) BT 以上来自于谷歌翻译 以下为原文 The short answer is no. The longer answer is: -There has been at least one paper I've seen that addresses part of this scope: http://www.cmpe.boun.edu.tr/~yurdakul/papers/BayarHiPEAC08.pdf (Dynamic Partial Self-Reconfiguration on Spartan-III FPGAs via a Parallel Configuration Access Port (PCAP)) -The current ISE PR software (9.2.04PR11) does not support Spartan-3. -The Spartan devices have many more limitations than devices like Virtex-4 with respect to the details here Some more information is here: http://www.xilinx.com/support/answers/18416.htm (6.3i Partial Reconfiguration - Is partial reconfiguration supported on Spartan-3/-3E devices?) http://forums.xilinx.com/xlnx/board/message?board.id=Virtex&thread.id=2446 (Dynamic Reconfigurable) http://forums.xilinx.com/xlnx/board/message?board.id=GenDis&message.id=991 (Does any virtex device allow reconfiguration of only just logic blocks, not whole column?) http://www.xilinx.com/support/answers/25018.htm (Partial Reconfiguration - PlanAhead Flow FAQ / Know Issues for the Early Access Partial PlanAhead Program) bt

我没有尝试使用Spartan-3E系列,但是使用Spartan-3可以构建一个可自我重构的嵌入式系统,包括微型激光器和其他外围设备。
使用ISE设计流程并不容易,因为它在某些方面失败了,但有一些解决方法 检查文件 Spartan-3上的自重构嵌入式系统 Canto,E。; Fons,F。; Lopez,M。; 现场可编程逻辑和应用(FPL 2008) 在Spartan-3上映射的嵌入式系统的自我重新配置 Canto,E。; Fons,F。; Lopez,M。; 重新配置以通信为中心的SoC(ReCoSoc 2008) 以上来自于谷歌翻译 以下为原文 I've not tried with Spartan-3E series, but with Spartan-3 it's possible to build a self-reconfigurable embedded system, with microblaze and other peripherals. It's not easy, using the ISE design flow because it fails in some points, but there are workarounds Check the papers Self-recofigurable embedded systems on Spartan-3 Canto, E.; Fons, F.; Lopez, M.; Field Programmable Logic and Applications (FPL 2008) Self-recofiguration of embedded systems on mapped on Spartan-3 Canto, E.; Fons, F.; Lopez, M.; Reconfiguration Communication-centric SoCs (ReCoSoc 2008) |

你好,
您说当前的ISE PR软件(9.2.04PR11)不支持Spartan-3。 是因为它不再为Spartan-3或其他原因提供总线宏? 在最后一种情况下,你能给我另一个限制吗? 我已经注意到PR模式下的PlanAhead无法识别斯巴达3的总线宏,但并不强制要求使用PlanAhead。 除了PlanAhead,如果我尝试在版本为9.2.04PR11的Spartan 3上进行部分重配置会怎样? 哪个版本的PR流量已经支持Spartan-3? 非常感谢您的回复! 罗穆亚尔德 以上来自于谷歌翻译 以下为原文 Hello, You said that the current ISE PR software (9.2.04PR11) does not support Spartan-3. Is it because it does not provides the bus macros for the Spartan-3 anymore or for other reason? In the last case, can you give me the other restriction? I already notice that PlanAhead in the PR Mode does not recognize the bus macro for the spartan 3, but it is not mandatory to use PlanAhead. Apart PlanAhead, what can happen if I try to do Partial Reconfiguration on Spartan 3 with the version 9.2.04PR11? Which version of the PR flows already support Spartan-3? Thanks a lot for your response! Romuald |

这篇文章相当陈旧,但它可能无法有效地改变任何东西。
目前的软件是11.4。 请注意,11需要特殊的PR许可证才能查看这些功能,并且访问权限通常仅限于少数现有客户。 上面的答案记录中提到的Spartan-3有许多硬件限制。 我会说实话,我没有亲自去看。 BT 以上来自于谷歌翻译 以下为原文 That post is fairly old, but it probably doesn't effectively change anything. The current software is 11.4. Note that 11 requires a special PR license for you to see these features and access is generally restricted to a small number of existing customers. There are a number of HW limitations for Spartan-3 mentioned in the Answer Record above. I'll be honest that I haven't looked at it further personally. bt

嗨,对于11.4,那是什么特殊的PR许可证以及如何获得/购买该许可证?
我正在使用virtex-5板.. 以上来自于谷歌翻译 以下为原文 hi, for 11.4, what special PR license is that and how do i get/buy that license? i am using a virtex-5 board.. |
