Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Chip designers have shown increasing interest in integrating specialized fixed-function coprocessors into multicore designs to improve energy efficiency. Recent work in academia [11, 37] and industry [16] has sought to enable more fine-grain offloading at the granularity of functions and loops. The sequential program now needs to migrate across the chip utilizing the appropriate accelerator for each program region. As the execution migrates, it has become increasingly challenging to retain the temporal and spatial locality of the original program as ll as manage the data sharing.    show that with the increasing energy cost of wires and caches relative to compute operations, it is imperative to optimize data movement to retain the energy benefits of accelerators.  develop FUSION, a lightight coherent cache hierarchy for accelerators and study the tradeoffs compared to a scratchpad based architecture.  find that coherency, both beten the accelerators and with the CPU, can help minimize data movement and save energy. FUSION leverages temporal coherence [32] to optimize data movement within the accelerator tile. The accelerator tile includes small per-accelerator L0 caches to minimize hit energy and a per-tile shared cache to improve localized-sharing beten accelerators and minimize data exchanges with the host LLC.  find that overall FUSION improves performance by 4.3× compared to an oracle DMA that pushes data into the scratchpad. In workloads with inter-accelerator sharing  save up to 10x the dynamic energy of the cache hierarchy by minimizing the host-accelerator data ping-ponging.
