摘要：
In a digital processing unit having a plurality of digital signal processors, a first digital signal processor can request a direct transfer of a signal group stored in the memory unit of a second digital signal processor. In order to insure that the second digital signal is active, a control signal is generated by the direct memory access controller of the first digital signal processor. The control signal is applied the directly to the memory access controller of the second digital signal processor. When the second digital signal processor is in an IDLE mode, the control signal activates the second digital signal processor.
