还没加驱动，不过这个应该简单了，呵呵！

整体感觉VDSP和bf561还是挺酷的，27M的L2_and_L3_common_memory.sm，uclinux.map.xml也有差不多27M，跑起来几乎没什么问题，就是下载速度变得慢了点，下载一次需要3-5分钟，不过无论如何都比用gcc toolchain编译下载要快，不是吗？

另外跑这样的大系统感觉最好有足够的内存和USB仿真器，使用了两个系统进行编译，一个是笔记本（1.6G CPU + 2G内存 + USB仿真器），另一个是台式机（sp3200 + 512M内存 + PCI仿真器），感觉用笔记本的速度要比台式机的快多了。

两个都是用的ADI的仿真器，哪天有机会搞个国产的仿真器试试，看看到底咋样，能不能经受住考验。哈哈！
