直接通过网页从官网下载速度超慢而且容易中断，尝试了几次不成功，于是改用阿里云主机下载，这个速度超快（有时能达到1MB/s），然后从云主机通过OSS方式下载到本地，解压安装（系统为Windows8 64bit），安装前要确认你的系统也是64位的，硬盘容量空出15GB左右，装起来比较快，看了下安装目录，SDSoC目录结构如下：
可见内置了Vivado ，Vivado_HLS，SDK三个开发工具，无需另外安装。另外也包含了arm-xilinx-Linux-gnueabi交叉编译工具，可完成Linux下的应用开发。
可参考这篇EETOP文章来安装license。
安装完成，双击桌面上的SDSoC图标：
启动画面：
Welcome界面（如果未显示，则点击菜单 Help -> Welcome进行显示：
点击Create SDSoC Project，创建一个SDSoC工程，弹出对话框如下：
输入工程名字test，工程路径默认，硬件平台选zed，操作系统选Linux，其余都不做修改，点Next：
这里选矩阵乘加的例子，点Finish，进入主界面如下：
用过Vivado HLS的能看出，二者工程界面基本布局相差不大。
直接点击Project -> Build All，经过几分钟，完成了编译、综合、生成bitstream、打包，在工程目录下可以看到生成的SD卡镜像文件：
将这些文件拷入空白的FAT32文件系统的SD卡即可查看运行情况。
从上面步骤看出，使用SDSoC开发Zynq应用，相当于使用IDE进行软件开发，再也不用在多个软件、工具之间来回跳转，只要一个集成开发环境就能完成所有必须的开发工作，从而提高了开发效率。
后面会深入研究如何进行程序优化，将PS上较为耗时的软件模块offload到PL中实现加速。

几天前试验，将SDDebug/sd_card/下的文件拷贝到SD卡，插入ZED Board后无法启动，一直怀疑是开发过程有问题。今天又尝试了下以前的旧镜像，居然也无法启动！看来是SD卡有问题。想起来之前安装Fedora 21时用这个SD卡做的镜像，有可能在起始扇区加入了一些不该有的东西。想到这里，就迅速切到Linux系统，用Disks工具对SD卡执行了低级格式化，将所有扇区都擦写了一遍，然后格式化为FAT文件系统，拷贝SDSoC镜像，插入板卡，居然启动成功了。。。
启动信息如下：
