The protection of Intellectual Property (IP) core for a Digital Signal Processing (DSP) kernel has become an important research area in the last few years for Consumer Electronics systems. The swelling threats of IP piracy, forgery, and counterfeiting and ownership abuse on DSP IP core are the principal reason behind that. This work investigates the impact of hardware steganography on protection of DSP IP core datapath against these threats. As a case study, the complete analysis of its impact on 8-point Discrete Cosine Transformation datapath architecture is presented.

硬件隐秘术对DSP内核数据路径的影响

在过去的几年中，数字信号处理（DSP）内核的知识产权（IP）内核保护已成为消费电子系统的重要研究领域。导致DSP IP内核出现IP盗版，伪造，伪造和所有权滥用等激增威胁的主要原因。这项工作研究了硬件隐写技术对防止这些威胁的DSP IP内核数据路径的保护的影响。作为案例研究，提供了其对8点离散余弦变换数据路径体系结构影响的完整分析。
