EPIC processor is one of the best ways to exploit the instruction level parallelism where multiple instructions are issued explicitly by the compiler. VLIW processor is the evolution of EPIC processing paradigm. Very Long Instruction Word (VLIW) is multi-issue processors that try to extract parallelism statically by the compiler .It execute a long instruction that consist of multiple operation....

Energy optimization is very important for portable and battery-driven embedded systems. With the shrinking of transistor sizes, reducing leakage power becomes a significant issue. In this paper, we propose a novel prediction approach to predict idleness of functional units for leakage energy management. Using a state-based predictor, historical utilization information of functional units (FUs) ...

there are different methods to reduce drag in high speed hulls. one of these methods is a change in the shape of the body by adding longitudinal side tunnels. in this paper it has been attempted to determine the influence of the tunnel height on hydrodynamic characteristics of the hull to achieving an optimum shape for the tunnel. to achieve this purpose, numerical simulation of the problem has...

In recent years, trimarans have been used in high-speed transport and warships, but studies of them made little progress. We designed a trimaran model it to perform water-entry experiment find way reduce the slamming pressure. The process entering water was divided into several steps, different theoretical models were for each step, together with their force analysis. Relying on our experimenta...

The article presents a method for calculating the mass load determining displacement of passenger trimaran vessels at initial stages design. state this issue has not been sufficiently studied to date, since there is no methodology that allows vessel. field research design vessels, in particular and purpose determine components total equations masses ships statistical dependencies are given, as ...
