To extend ESPIM's techniques to handle structured sparsity patterns, we can modify the fine-grained interleaving layout and the decoupled prefetching mechanisms. For structured sparsity, where certain patterns of zeros are known in advance, we can design specific indexing schemes that cater to these patterns. By organizing the matrix cells and indices based on the structured sparsity pattern, we can optimize the layout to efficiently handle the specific sparsity structure. Additionally, the decoupled prefetching can be adapted to prioritize fetching elements based on the known structured sparsity pattern, reducing unnecessary prefetching and improving efficiency in matching vector elements to matrix cells.
