Multiprocessor interface with dynamic duty management ability and its program loading/unloading method

A multi-processor interface with dynamic work managing capacity and a program unloading method are provided. The method is suitable for use in the microprocessor unit configuration (Micro Processor Unit, MPU) and digital signal processors (Digital Signal Processor, DSP) between communication interface and dynamic management microprocessor unit assigned to the digital signal processor to deal with the work. First of all, the search for digital signal processors in the implementation of the idle unit, then the above-mentioned work of one of a number of threads to the execution unit scheduled for the final implementation of the unit to start this thread to perform. Accordingly, the hardware cost can be saved, the effective multi-core processors to enhance the effectiveness of communication.
