Power optimizations for transport triggered SIMD processors
—Power consumption in modern processor design is a key aspect. Optimizing the processor for power leads to direct savings in battery energy consumption in case of mobile devices. At the same time, many mobile applications demand high computational performance. In case of large scale computing, low power compute devices help in thermal design and in reducing the electricity bill. This paper presents a case study of a customized low power vector processor design that was synthesized on a 28 nm process technology. The processor has a programmer exposed datapath based on the transport triggered architecture programming model. The paper’s focus is on the RTL and microarchitecture level power optimizations applied to the design. Using semiautomated interconnection network and register file optimization algorithm, up to 27% of power savings were achieved. Using this as a baseline and applying register file datapath gating, register file banking and enabling clock gating of individual p...
