Based on the analysis of typical hybrid-type content addressable memory (CAM) structures, a hybrid-type CAM architecture with lower power consumption and higher stability was proposed. This design changes the connection of a N-type metal-oxide-semiconductor (NMOS) transistor in the control circuit, which greatly reduces the power consumption during comparison by making the match line simply discharge...
To reach necessary end-to-end connectivity between the Internet and wireless sensor networks (WSNs), the Internet Engineering Task Force (IETF) IPv6 over low power wireless personal area network (6LowPAN) working group has been established and introduced an adaptation layer for integration of IEEE 802.15.4 physical layer/media access control (PHY/MAC) layers and the upper layers of any Internet protocol...
To make speech watermarking achieve both copyright protection and integrity verification, a novel multipurpose speech watermarking algorithm based on the multistage vector quantization (MSVQ) of linear prediction coefficients (LPCs) is presented in this article. The property of natural speech that the vector quantization (VQ) indices of the LPCs amongst neighboring frames tend to be very similar is...
