MP3频率样值解码处理的建模与仿真 [摘要] SystemC是一门新的面向软/硬件协同设计的编程语言，提供支持硬件建模和仿真C++类库及相应的仿真内核。在设计的过程中可采用SystemC来统一描述硬件、软件和它们的接口，实现软硬件的协同设计和仿真。 MPEG-1 Layer3编解码算法具有压缩比高、声音质量好、算法复杂度适中的优点，在数字声音的存储、因特网上的多媒体传输等领域得到广泛的应用。随着网络MP3音乐的流行，一种便携式的MP3播放器开始出现，作为一种消费类电子产品，具有极好的市场前景。 本论文的工作目标就是介绍SystemC语言并在此基础上给出其在MP3解码算法中的应用，具体内容如下： 1． 本文首先介绍SystemC语言的产生背景、特点以及基本语法。 2． 然后对MP3解码算法进行介绍，对标准进行了一些分析。 3． 最后通过SystemC语言对MP3频率样值解码处理的建模简要说明SystemC的建模和仿真方法。 [关键词] SystemC MP3解码 算法验证 解码器 片上系统 [Abstract] SystemC is a new programming language orienting to software/hardware co-design, providing C++ class library and the simulation kernel to support hardware modeling and simulation. During the design, SystemC can be used to describe software, hardware and their interface, to do hardware/software co-design and co-simulation. MPEG-1 Layer3 has the advantages of high compressing ratio, excellent audio quality and moderate algorithm complexity. So it is widely used in digital audio store, multimedia data transmission over the internet, etc. Along with the popularity of MP3 music based on the Internet, a portable MP3 player is introduced which has excellent market value as a consumer electronic product. The purpose of the paper is introducing the SystemC language and then giving an application of algorithm implement of MP3 decoding. The main contents are as follows: 1. The paper firstly introduces the background, characteristics and basic syntax of SystemC. 2. In the second part, The paper introduces the algorithm of MP3 decoding and analyzes the standard. 3. In the last place, The paper demonstrates the modeling and emulating method of SystemC language through the appliation of SystemC in the moduling of MP3 frequency sample decoding.
