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定制指令用戶指南：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可執行文件的鑲入式程序的編寫方法及示例(鑲入式后門程序&原程序) 由于Microsoft公司的Windows系統是當前大部分個人電腦所使用的操作系統 主要包括win95,98,me,nt4,2000,xp等，而這些系統所使用的可執行文件的格式基 本上是PE結構的。這里的可執行文件的鑲入式程序就是針對PE結構的可執行文件。 這里先簡單說一下PE文件框架結構： DOS MZ header DOS stub//在不支持 PE文件格式的操作系統中它將簡單顯示一個錯誤提示 PE header//含了許多PE裝載器用到的重要信息 Section table//每個Section的信息 Section 1 Section 2 Section 3.... 由于SectionAlignment 塊對齊的原因每個Section之間都會產生很多空間， 鑲入式程序的代碼可以放在Section之間的空位上，比較方便的方法是把代碼放在 最后一個Section的末尾，然后更改Misc.VirtualSize和SizeOfRawData這兩個位 于Section table的IMAGE_SECTION_header結構數組的成員。如果代碼十分的長， 有時候會造成鑲入的代碼無法被完全加載而產生錯誤，這時需要更改SizeOfImage 在IMAGE_NT_headerS 結構中。 在不同的WINDOWS版本中api調用地址也有不同，為了解決這個問題可以更改引 入表讓加載器

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.)
