(a) von Neumann architecture with separate processing and memory units, LIM: memory blocks can perform logic, and SLIM: all memory blocks capable to perform Storage and Logic operations simultaneously and non-destructively, (b) Ideal computing system with LIM/SLIM co-existing with von Neumann CPU, enabling computation at all levels of memory hierarchy.
