Keywords: | Adaptive multi-thread; Component; Configurable memory array; Frequency scaling; Low power GPU; Stream processor; Unified shader | Issue Date: | 2008 | Journal Volume: | 1 | Source: | 2008 International SoC Design Conference, ISOCC 2008 | Abstract: | This paper presents a graphics processing unit with energy-saving techniques. Several techniques and architectures are proposed to achieve high performance with low power consumption. First of all, low power core pipeline is designed with 2-issue VLIW architecture to reduce power consumption while achieving the processing capability of 400MFLOPS or 800MOPS. In addition, inter/intra adaptive multi-threading scheme can increase the performance by increasing hardware utilization, and the proposed configurable memory array architecture can reduce off-chip memory accessing frequency by caching both input data and output results. Furthermore, for graphics applications, a geometry-content-aware technique called early-rejection-after-transformation is proposed to remove redundant operations for invisible triangles. As for circuit level power reduction, power-aware frequency scaling is proposed to further reduce the power consumption. ©2008 IEEE. |
