The overall research includes the parameterized architecture of the DSP core, multi-function data-path, input/output modes for embedded applications, low-power techniques, optional special function blocks and module generator. Parameterized DSP core is designed for optimal usage of different requirements in system applications. Owing to the parameterized structure, the DSP core can be custom made for dedicated system with parameters setting. The parameterized DSP core is especially suitable for an embedded system. The primary application is digital signal processing system which designed to achieve demodulation/synchronization with better performance and flexibility. We set up a novel design flow of embedded parameterized DSP core. The design flow includes a newly designed flexible parameterized DSP core structure, a module generator and a methodology to build the DSP core with optimal performance. The features in this DSP core include parameterized data-path, dual MAC unit, sub-word MAC and optional function-specific blocks for accelerating communication system modulation operations. This DSP core also has a low power structure, which includes the gray code addressing mode, pipeline sharing and a novel buffered hardware looping. Users can select the parameters and special function blocks based on the specification of their applications and then a synthesizable DSP core is generated in a proposed module generator with graph user interface. The proposed DSP core and the synthesizable RTL code have been verified with TSMC 0.35um SPQM, 0.25um 1P5M cell based and FPGA design flow.
