Recent research has introduced a novel architecture, called ProVet, to improve energy efficiency in high-performance hardware accelerators for data-intensive workloads. The architecture is built from a modular building block, called a Tile, and achieves high performance and energy efficiency through two key innovations: software-based Single-Instruction Multiple-Data (Soft-SIMD) functional units and Very Wide Registers (VWRs). Soft-SIMD units enable parallel operations with fine-grained, software-configurable data bit-widths. They rely on simple shift-adder logic, reducing energy consumption compared to conventional architectures. Complementing this, VWRs act as high-bandwidth buffers between large memories and local registers, mitigating the energy cost of frequent memory accesses. Their very wide structure and single-bit data lines reduce hardware complexity and wire interconnections, which is critical for energy efficiency.
