Apparatus and method for the transfer of signal groups between digital signal processors in a digital signal processing unit

摘要

In a digital signal processing unit including at least two digital signal processors, 30, 30' an interface unit 31, 31' is added to each digital signal processor to implement transfer of signal groups between the digital signal processors 30, 30'. The interface unit 31, 31' receives the signal groups to be transferred from the direct memory access controller 34, 34' of the digital signal processor 30, 30' providing the signal groups. The interface unit 31, 31' then transfers the signal groups to the direct memory access controller 34, 34' of the second digital signal processor, the digital signal processor requiring the signal groups. The direct memory access controllers 34, 34' receive control signals from the interface units 31, 31' that support the signal group transfer.
