Title
Performance evaluation of ring-structure register file in multimedia applications
Abstract
As the concurrent functional units in media processors increase continuously to meet the performance needs, the required access (i.e. read or write) ports of the centralized register file (RF) multiply rapidly and cannot be efficiently implemented. We propose a novel ring-structure RF, which is composed of register sub-blocks identical to the RF for a single functional unit. Data exchanges among functional units occur on the switch network of the ring registers. The proposed RF has been integrated into a four-way VLIW DSP processor successfully that demonstrates its effectiveness in DSP kernels. The synthesis result shows that our proposed ring-structure RF saves 91.88% silicon area of the centralized one, while reducing its access time by 77.35%.
