Varifocal storage (VS) presents a new architecture that coordinates application demands, hardware accelerators, and intelligent data storage devices to efficiently support various input resolutions of system components, but still maintain the flexibility and quality without additional costs. Instead of faithfully shipping the raw data, the cross-layer design of VS allows an intelligent storage device to work directly with the running application to generate and deliver data sets in the desired resolution and quality before going through the narrower system interconnect. In this way, VS minimizes the bandwidth demand from the data source and allows hardware accelerators to work on received data without additional preprocessing. Without programmers’ hints, VS achieves 1.46× speedup on a computer with approximate hardware accelerators.

变焦存储：动态多分辨率数据存储

变焦存储 (VS) 提出了一种新架构，可协调应用需求、硬件加速器和智能数据存储设备，以有效支持系统组件的各种输入分辨率，但仍保持灵活性和质量，无需额外成本。VS 的跨层设计不是忠实地传送原始数据，而是允许智能存储设备直接与正在运行的应用程序一起工作，以在通过更窄的系统互连之前以所需的分辨率和质量生成和传送数据集。通过这种方式，VS 最大限度地减少了数据源的带宽需求，并允许硬件加速器处理接收到的数据，而无需额外的预处理。在没有程序员提示的情况下，VS 在具有近似硬件加速器的计算机上实现了 1.46 倍的加速。
