Virtual double width accumulators for vector processing

摘要

A processing system includes left and right data path processors configured to concurrently receive parallel instructions. Left and right accumulators which are, respectively, disposed in the left and right data path processors, are configured to execute an accumulate instruction and obtain an accumulation value. Left and right local memories (LMs) are coupled to the left and right accumulators and configured to store the accumulation value. The accumulation value is equally divided for storage in the left LM and the right LM.
