The multiply clock domain (MCD) technique is a novel technique to compromising between synchronous systems and asynchronous systems to reduce the power. However, most present studies of MCD are based on superscalar architectures. In this paper, MCDE, a MCD technique based on explicitly parallel instruction computing (EPIC) architecture is designed and implemented to reduce the power of clock di...

This paper proposes microarchitecture-driven dynamic voltage scaling as a viable solution to power efficient architectures, with little or no performance penalty. The run-time behavior exhibited by common applications, with active periods, alternated with stall periods due to cache misses, is exploited to reduce the dynamic component of power consumption via selective voltage scaling. As it is ...

This paper presents a novel implementation of an embedded Java microarchitecture for secure, realtime, and multi-threaded applications. Together with the support of modern features of object-oriented languages, such as exception handling, automatic garbage collection and interface types, a general-purpose platform is established which also fits for the agent concept. Especially, considering rea...

Computer architects heavily rely on simulation tools during the design process of their next generation processor. Statistical simulation allows for making quick performance estimates early in the design cycle. However, the current state-of-the-art in statistical simulation still uses microarchitecture-dependent cache models which is impractical when exploring cache hierarchy design spaces. Thi...

The ever-growing microarchitecture complexity of processors creates a widening gap between the verification plan and the test generation technologies used in its implementation. This gap impacts the cost and quality of the verification process. To overcome this, we introduce a novel test generation platform for processor verification. This approach is based on a scenario description language th...

High-performance miniature power sources could enable new microelectronic systems. Here we report lithium ion microbatteries having power densities up to 7.4 mW cm(-2) μm(-1), which equals or exceeds that of the best supercapacitors, and which is 2,000 times higher than that of other microbatteries. Our key insight is that the battery microarchitecture can concurrently optimize ion and electron...

I will argue in this work that because of the flexibility offered by the field programmable devices, such as FPGA, the instruction set design becomes an essential part of designing digital systems of the future. There are advantages to experiment with microarchitecture and instruction set design to fit various applications. I will illustrate by a series of evolution of instruction set design fo...

We develop and evaluate a novel 3D computational bone framework, which is capable of enabling quantitative assessment of bone micro-architecture, bone mineral density and fracture risks. Our model for bone mineral is developed and its parameters are estimated from imaging data obtained with dual energy x-ray absorptiometry and x-ray imaging methods. Using these parameters, we propose a proper 3...
