Abstract: The invention discloses a universal computing digital signal processor which comprises a CPU core unit, a DSP core unit, a multi-layer interconnection structure, an in-chip share storage array, an off-chip memory interface, a high-speed input and output interface, a second high-speed input and output interface, an inter-chip direct connection interface and an inter-core synchronous device. The CPU core unit comprises a plurality of CPU cores. The DSP core unit comprises a plurality of DSP cores. The CPU cores and the DSP cores are respectively connected with the in-chip share storage array through the multi-layer interconnection structure. The CPU cores are connected with the first high-speed input and output interface. The DSP cores are connected with the second-speed input and output interface and the inter-chip direct connection interface. The application program of the universal computing digital signal processor is obtained in a mode that uniform compiling and linking are conducted on CPU end object codes and DSP end object codes obtained in a compiling mode through a uniform and parallel programming method. The universal computing digital signal processor can maintain the basic characteristics of an embedded type DSP and the advantages of high performance and low consumption, and can effectively support universal scientific calculation.
