XC6SLX9-2TQG144C和MCB疑问

2090 MCB

问答对人有帮助，内容完整，我也想知道答案 0 嗨，我对XC6SLX9-2TQG144C和MCB有疑问。该FPGA具有-2速度等级和TQG144封装。 Spartan-6 FPGA存储器控制器（UG388）表示，TQG144封装不支持MCB。 Spartan-6系列概述（DS160）只是表示无论封装如何，-3N速度等级都不支持MCB。哪一个是正确的？或者DS160是指所有-3N速度级FPGA + TQG144封装FPGA？除了TQG144之外的其他封装都不相关，因为我无法安全地焊接它们。如果这个FPGA不兼容MCB，你能告诉我另一种可能以相当快的速度存储多达30兆位的方法吗？以上来自于谷歌翻译以下为原文 Hi, I have a question regarding the XC6SLX9-2TQG144C and MCB. This FPGA has a -2 speed grade and TQG144 package. The Spartan-6 FPGA Memory Controller (UG388) says, that the TQG144 package does not support MCB. The Spartan-6 Family Overview (DS160) just says that -3N speed grade does not support MCB regardless of the package. Which one is correct? Or does the DS160 means all -3N speed grade FPGA + TQG144 package FPGA? Other packages than the TQG144 aren't relevant, because i can't solder them safely. If this FPGA isn't MCB compatible, can you tell me another possible way to store up to 30 Mbits with a decent speed? 0

答案对人有帮助，有参考价值 0 kantner写道：一世，我对XC6SLX9-2TQG144C和MCB有疑问。该FPGA具有-2速度等级和TQG144封装。 Spartan-6 FPGA存储器控制器（UG388）表示，TQG144封装不支持MCB。 Spartan-6系列概述（DS160）只是表示无论封装如何，-3N速度等级都不支持MCB。哪一个是正确的？或者DS160是指所有-3N速度级FPGA + TQG144封装FPGA？这些要求并不是唯一的。他们都是正确的。这是一个简单的布尔OR。或者是AND。 DeMorganize它。如果打包/ = TQ144，则速度/ = -3N MCB 那么，首先你需要定义“体面的速度”。 30 Mb并不多。您可以将SDR DRAM芯片连接到FPGA并滚动自己的控制器。这就是我要做的。 ----------------------------是的，我这样做是为了谋生。以上来自于谷歌翻译以下为原文 kantner wrote: i, I have a question regarding the XC6SLX9-2TQG144C and MCB.

Or does the DS160 means all -3N speed grade FPGA + TQG144 package FPGA? Those requirements aren't exclusive. They are both correct. It's a simple boolean OR. Or an AND. DeMorganize it. if package /= TQ144 and speed /= -3N then MCB <= true; else MCB <= false; end if; Other packages than the TQG144 aren't relevant, because i can't solder them safely. If this FPGA isn't MCB compatible, can you tell me another possible way to store up to 30 Mbits with a decent speed? Well, first you need to define "decent speed." And 30 Mb isn't much. You could probably just connect an SDR DRAM chip to the FPGA and roll your own controller. That's what I'd do. ----------------------------Yes, I do this for a living.
