Memory virtualization plays an important role in system virtualization. However, traditional memory virtualization solutions are usually for those architectures with hardware-managed TLBs, such as x86, ARM and so on. The solutions for architectures with software-managed TLBs are rarely mentioned. This paper presents three different memory virtualization solutions for architectures with software-managed...
This paper presents a floating-point fused multiply-add (FMA) unit with low-cost and low power techniques. To improve the performance, two single-precision operations can be performed concurrently with one double-precision datapath, which is very useful in multimedia and even scientific applications. Moreover, to reduce the additional area costs for supporting two single-precision operations in parallel,...
This paper presents a methodology for high-level power modeling of cell-based processors. A flexible power model library, which can automatically generate detailed power data for actual circuits of each part of given processor, is developed and annotated dynamically for architecture-level power simulator. According to this method, the dynamic power, leakage power and even area and cell counts can...
This paper introduces a new way-prediction scheme for achieving low energy consumption and high performance for set-associative instruction cache. The proposed scheme is based on the different cases of how program execution proceeds. By predicting for the sequential instruction flow and non-sequential one respectively, we can achieve a high way prediction hit rate. Since way-prediction doesnpsilat...
