YHFT-QDSP: High-Performance Heterogeneous Multi-Core DSP

Multi-core architectures are widely used to enhance the microprocessor performance within a limited increase in time-to-market and power consumption of the chips.Toward the application of high-density data signal processing, this paper presents a novel heterogeneous multi-core architecture digital signal processor(DSP),YHFT-QDSP,with one RISC CPU core and 4 VLIW DSP cores.By three kinds of interconnection,YHFT-QDSP provides high efficiency message communication for inner-chip RISC core and DSP cores,inner-c...
