DDR2 SDRAM 控制器的FPGA实现-DDR2 SDRAM controller FPGA to achieve

包含32为乘法器的设计，用verilog语言实现，包括booth编码的实现，booth乘法器的实现，3_2压缩器的实现，4_2压缩器的实现，华伦斯树的实现，以及两个testbench文件用于测试。(Contains 32 multiplier design, verilog language, including booth encoding implementations, booth multiplier implementations, 3_2 compressor implementation 4_2 compressor to achieve and realize China Clarence tree, and two testbench file with the to the test.)

Verilog经典教程，很好的学习Verilog的书籍，对学习硬件编程很有帮助。(Verilog classic handbook, good learning Verilog books, to learn hardware programming helpful.)

这个文件中是UltraEdit的一些格式化文件说明 由于原来的 UltraEdit 不支持 HDL 语言的格式化显示，把文件解压得到的 wordfile.txt替换其安装目录下的 wordfile.txt 文件即可-This document is formatted UltraEdit document describes some of the original UltraEdit as a result of HDL does not support formatting language shows that the document received decompression wordfile.txt replace its installation directory under the document can wordfile.txt

研究信道噪声对M-ary QAM的影响，适合数字通讯从业者(Effect of channel noise on M-ary QAM in)

This tutorial presents some basic concepts that can be helpful in debugging of application programs written in the Nios II assembly language, which run on Altera’s DE2 boards.

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec-This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the
