The goal for this chapter is to introduce you to Java's native methods. If you are new to Java, you may not know what native methods are, and even if you are an experienced Java developer, you may not have had a reason to learn more about native methods. At the conclusion of this chapter you should have a better understanding of what native methods are, when and why you may want to use them, and the consequences of using them. You should also have a basic understanding of how native methods work...

Xilinx MicroBlaze的使用方法 建立一个ISE的工程，工程的顶层文件为schematic的。然后根据实际需要添加自己的逻辑或处理部分。Microblaze可以像一个IP一样同时应用到自己的设计中去。具体方法如下： 1、在工程中选择Add Source,在选择框中选择Embedded Processor，假设为该处理器起名为Microblaze_xxx。 2、此时ISE会自动启动XPS，在XPS中根据导向设置自己的Microblaze_xxx处理器的参数，并生成网表（注意必须在EDK中生成）。 3、选中Microblaze_xxx，双击View HDL Instantiation Template 生成例化文件。如果要使得Microblaze的管脚既...
