Abstract
A processing system allocates memory to co-locate input and output operands for operations for processing in memory (PIM) execution in the same PIM-local memory while exploiting row-buffer locality and complying with conventional memory abstraction. The processing system identifies as 'super rows' virtual rows that span all the banks of a memory device. Each super row has a different bank-interleaving pattern, referred to as a “color”. A group of contiguous super rows that has the same PIM-interleaving pattern is referred to as a “color group”. The processing system assigns memory addresses to each operand (e.g., vector) of an operation for PIM execution to a super row having a different color within the same color group to co-locate the operands for each PIM execution unit and uses address hashing to alternate between banks assigned to elements of a first operand and elements of a second operand of the operation.
