==DATA CO-LOCATION USING ADDRESS HASHING FOR HIGH-PERFORMANCE PROCESSING IN MEMORY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240111672 titled 'DATA CO-LOCATION USING ADDRESS HASHING FOR HIGH-PERFORMANCE PROCESSING IN MEMORY

==Simplified Explanation==

The abstract describes a processing system that allocates memory to co-locate input and output operands for operations in memory execution, utilizing row-buffer locality and conventional memory abstraction. The system identifies "super rows" that span all banks of a memory device, each with a different bank-interleaving pattern or "color." A group of contiguous super rows with the same PIM-interleaving pattern is called a "color group." Memory addresses are assigned to operands of an operation to co-locate them in super rows with different colors within the same color group, alternating between banks using address hashing.

* Memory allocation system for co-locating input and output operands in memory execution
* Utilizes super rows with different bank-interleaving patterns or "colors"
* Assigns memory addresses to operands within the same color group for efficient processing
* Utilizes address hashing to alternate between banks for different operands

==Original Abstract Submitted==

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.
