With the Altera Nios II embedded processor, you as the system designercan accelerate time-critical software algorithms by adding custominstructions to the Nios II processor instruction set. Using custominstructions, you can reduce a complex sequence of standard instructionsto a single instruction implemented in hardware. You can use this featurefor a variety of applications, for example, to optimize software innerloops for digital signal processing (DSP), packet header processing, andcomputation-intensive applications. The Nios II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphicaluser interface (GUI) used to add up to 256 custom instructions to theNios II processor

Nios II定制指令用户指南：With the Altera Nios II embedded processor, you as the system designer can accelerate time-critical software algorithms by adding custom instructions to the Nios II processor instruction set. Using custom instructions, you can reduce a complex sequence of standard instructions to a single instruction implemented in hardware. You can use this feature for a variety of applications, for example, to optimize software inner loops for digital signal processing (DSP), packet header processing, and computation-intensive applications. The Nios II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphical user interface (GUI) used to add up to 256 custom instructions to the Nios II processor. The custom instruction logic connects directly to the Nios II arithmetic logic unit (ALU) as shown in Figure 1–1.

PE可执行文件的镶入式程序的编写方法及示例(镶入式后门程序&原程序) 由于Microsoft公司的Windows系统是当前大部分个人电脑所使用的操作系统 主要包括win95,98,me,nt4,2000,xp等，而这些系统所使用的可执行文件的格式基 本上是PE结构的。这里的可执行文件的镶入式程序就是针对PE结构的可执行文件。 这里先简单说一下PE文件框架结构： DOS MZ header DOS stub//在不支持 PE文件格式的操作系统中它将简单显示一个错误提示 PE header//含了许多PE装载器用到的重要信息 Section table//每个Section的信息 Section 1 Section 2 Section 3.... 由于SectionAlignment 块对齐的原因每个Section之间都会产生很多空间， 镶入式程序的代码可以放在Section之间的空位上，比较方便的方法是把代码放在 最后一个Section的末尾，然后更改Misc.VirtualSize和SizeOfRawData这两个位 于Section table的IMAGE_SECTION_header结构数组的成员。如果代码十分的长， 有时候会造成镶入的代码无法被完全加载而产生错误，这时需要更改SizeOfImage 在IMAGE_NT_headerS 结构中。 在不同的WINDOWS版本中api调用地址也有不同，为了解决这个问题可以更改引 入表让加载器

linux 的引导程序源码The Microsoft® Windows® Software Development Kit (SDK) provides the documentation, samples, header files, libraries, and tools you need to develop applications that run on Windows. The applications you develop with this edition of the SDK can run on the x86, x64 and Itanium-based versions of Windows Server 2003 SP1, Windows XP SP2, Windows XP x64 Pro Edition, and Windows 2000. A new custom install allows you to select components you wish to install on a more granular level.

The tar file contains the following files: ptfsf.c: heart of the perfect TFSF code ptfsf.h: header file for same ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in the paper ptfsf-file-maker.c: code to generate an incident-field file using the "perfect" incident fields ptfsf-demo-file.c: FDTD code which uses the perfect incident fields stored in a file fdtdgen.h: defines macros used in much of my code Makefile: simple make-file to compile programs Also include are some simple script files to run the programs with reasonable values. The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.)
