DVD伺服控制芯片中内容加扰系统的硬件结构

Hardware Architecture of a Content Scrambling System for DVD Servo Controller

本文介绍了一种用于DVD ROM伺服控制芯片的内容干扰系统 (CSS)的硬件结构 .该系统通过在DVD驱动器和主机之间进行认证和对密钥进行加扰 ,可有效防止对DVD盘片的非法拷贝 .用VerilogHDL完成整个系统的设计 ,功能仿真结果表明 ,设计成功 .采用CMOS标准单元库的综合结果为 :CSS的最大时钟频率为 10 0MHZ ,面积为1.6 9mm2 (0 .2 5 μm) ,当CSS的频率为 10 0MHZ时功耗为 37.38mW ,其性能足以满足DVD应用 .

This paper presents the hardware architecture for a Content Scrambling System (CSS) that can be used as a building block for DVD-ROM servo controller. It is designed to prevent illegal copy of DVD disc. This includes performing the authentication between DVD drive and the host and scrambling the keys. The system has been implemented in Verilog HDL and the simulation results indicate that the design is successful. Synthesis for a 0.25 μm standard-cell library provides an estimation of 100 MHZ achievable clock-frequency, 1.69 mm2 and 37.38 mW power dissipation. It has sufficient performance for DVD applications.
