Abstract
A Procesor-In-Memory (PIM) includes a digital accelerator for image and graphics processing. The digital accelerator is based on an ALU having multipliers for processing combinations of bits smaller than those in the input data (e.g., 4×4 adders if the input data are 8-bit numbers). The ALU implements various arithmetic algorithms for addition, multiplication, and other operations. A secondary processing logic includes adders in series and parallel to permit vector operations as well as operations on longer scalars. A self-repairing ALU is also disclosed.
