DATA PROCESSING SYSTEM AND METHOD FOR INTERCONNECT ARBITRATION |
摘要 |
<p>A data processing system includes processing units for processing data, at least one memory for storing data from the processing units, an interconnect for connecting the processing units and the memory. The processing units request write access to the memory via the interconnect to write data into the memory. At least one arbiter performs interconnect arbitration for the access to the memory from the processing units, wherein interconnect arbitration is performed based on the minimum logic level changes of the interconnect as introduced by the write accesses of the processing units to the memory. If more than one write request is available from different processing units the interconnect arbitration (interconnect access), is granted to that processing unit, whose data to be sent to the memory via the interconnect results in minimum logic level changes to the interconnect. Power dissipation due to switching of logic levels is reduced.</p> |
