The value of run-time application power consumption in the full system is a prerequisite for energy optimization. Though past studies have demonstrated the use of performance events for building single component (CPU, Memory, Disk) power model, we propose a method to estimate application power consumption in the full system with performance events. In this paper, we identify different stress on components...
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,...
