EDA技术以EDA软件工具为开发环境，以可编程逻辑器件为实验载体，实现源代码编程和仿真功能。VHDL作为一种标准化的硬件描述语言用于描述数字系统的结构、行为、功能和接口。本设计提出了一种基于VHDL语言的编码器和译码器的实现方法。编码器与译码器是计算机电路中基本的器件，本课程设计采用EDA技术设计编码和译码器。编码器由8线-3线优先编码器作为实例代表，译码器则包含3线-8线译码器和2线-4线译码器两个实例模块组成。课程设计采用硬件描述语言VHDL把电路按模块化方式进行设计，然后进行编程、时序仿真和分析等。课程设计结构简单，使用方便，具有一定的应用价值。 (EDA technology take the EDA software as tools for the development of the environment,programmable logic devices in experimental carrier,the realiztion of the source code programming and simulation. The VHDL as a standardized hardware description language used to describe the struction of digital systems,behavior,function and interface. The paper proposes a method for encoder and decoder based on the VHDL language.Encoder and decoder is a basic computer circuit devices.This Curriculum design by EDA design encoder and decoder.Encoders from 8- 3 priority encoder for example,and decoder includes 3- 8 decoder and the 2- 4 examples of the two decoder modules.And then to program, the timing simulation and analysis.Curriculum design, simple structure, easy to use and has a value.)

ASIC Design using VHDL by Shyam Mani

应用背景在本文中，我们提出了流水线的吞吐量的AES-GCMkaratsuab人基于有限域乘法器。与我们提出的四级子二次有限域乘法器，Ghash功能不在GCM任何瓶颈硬件系统，无论三的AES实现哪一个提高吞吐量的AES-GCM流水线Karatsuba乘法器203（基于BlockRAM SubBytes，复合场SubBytes或基于LUT的SubBytes）。这个提出的AES-GCM芯达到31gbps和39gbps Virtex4吞吐量和Virtex5，分别。实验结果表明，一个单一的现代FPGA芯片能提供超过了认证的AES-GCM 30Gbps的吞吐量，具有高性能计算领域可编程器件的优点系统。关键技术在AES-GCM的两种主要成分（高级加密标准伽罗瓦计数器模式）是一个AES引擎和一个有限域乘法器GF（2128）在通用散列函数（GHash）。因为固有的计算反馈，系统性能通常由有限的基于FPGA实现的已知域乘法器的日期。在本文中，我们目前的吞吐量优化的AES-GCM 4级流水线基于FPGA的Karatsuba-Ofman算法的有限域乘法器。关键流水线乘法器的延时然后匹配的AES实现无论BLOCKRAM SubBytes，流水线复合场SubBytes或基于LUT的字节。AES-GCM吞吐量超过30Gbps上一个单一的Xilinx Virtex芯片。实验结果表明，我们实现迄今为止最有效的AES-GCM FPGA实现。

Synchronous DRAM (SDRAM) has become a mainstream memory of choice in embedded system memory design due to its speed, burst access and pipeline features. For high-end applications using processors such as Motorola MPC 8260 or Intel StrongArm, the interface to the SDRAM is supported by the processor’s built-in peripheral module.
