Future high-end SoC applications will require huge computation and communication capabilities, which are provided by multiple processing cores integrated by on-chip communication architecture. Network-on-chip (NoC) provides a structured way of realizing inter-core communications on silicon for highly parallel SoC. The design of our CHNoC (cluster-based(More)
The combination of Unified Modeling Language (UML) and SystemC has led to an object-oriented high-level design automation methodology. In this paper, a novel bi-directional UML-SystemC translation tool <i>UMLSC</i> is proposed. Specifically, a set of principles for modeling SystemC design in UML and an algorithm for UML-SystemC bi-directional translation(More)
Conventionally, subcarrier based beamforming was used in an OFDM (Orthogonal Frequency Division Multiplexing) system under MIMO (Multiple-Input and MultipleOutput) channels to achieve optimal performance, where many DFT/IDFT (Discrete Fourier Transform/Inverse DFT) blocks, each corresponding to one antenna, are required. To reduce the complexity induced by(More)
Subcarrier based space processing was conventionally employed in Orthogonal Frequency Division Multiplexing (OFDM) systems under Multiple-Input and Multiple-Output (MIMO) channels to achieve optimal performance. At the receiver of such systems, multiple Discrete Fourier Transform (DFT) blocks, each corresponding to one receive antenna, are required to be(More)
An M-ary Orthogonal Pulse Polarity Modulation (OPM) using modified Orthogonal Variable Spreading Factor codes (OVSF), i.e., a set of orthogonal Walsh codes, for time hopping ultra wideband (TH-UWB) communication systems is proposed. Under FCC power spectrum density (PSD) constraint for UWB, the proposed M-ary OPM system proves to be more power efficient(More)
