Abstract
In a data processing system including a plurality of digital signal processor subsystems, selected peripheral components are shared by the digital signal processor subsystems. In particular, the high level data link controller is shared by the subsystems. Using a first interrupt signal after each transfer of signal groups from the peripheral direct memory access unit, the data can be efficiently transferred from a channel memory of the peripheral direct memory access unit to the high level data link controller. A second interrupt from the high level data link controller when a last word of a packet is transferred thereto causes a new channel memory to be accessed. An abort signal is generated when a signal group for a packet being processed by the high level data link controller is not available in a timely manner.
