Numerical optimization of an inverted-bow trimaran is carried out through three simulation-based design (SBD) frameworks. Different positions the trimaran’s side hull are investigated based on a computational fluid dynamics solver using non-dominated sorting genetic algorithm-III (NSGA-III), simultaneous hybrid exploration that robust, progressive and adaptive (SHERPA) response surface (RS) mul...

It has been widely known that a significant part of the bits are useless or even unused during the program execution. Bit-width analysis targets at finding the minimum bits needed for each variable in the program, which ensures the execution correctness and resources saving. In this paper, we proposed a static analysis method for bit-widths in general applications, which approximates conservati...

Reducing memory accesses is particularly important for DSP applications since they are widely used in embedded systems and need to be executed with high performance and low power consumption. In this paper, we focus on optimizing loops which are the most critical sections for DSP applications. We propose a machineindependent intermediate-code-level loop memory access optimization technique, REA...

With a rapid increase in various number of marine tourism destinations, especially The Bunaken National Park with the amount tourists that has increased throughout year rising by 23% for domestic and 12% international between 2002 2018. Unfortunately, to enjoy underwater scenery can access diving snorkeling which is not all tourist do that. Furthermore, order support industry Indonesia, semi-su...

This paper presents a unified algorithm that addresses the instruction scheduling and register allocation problems for high performance processor architectures. Our proposal is based on the subgraph isomorphism theory. Given a Directed Acyclic Graph (DAG) G1, the algorithm looks for a subgraph G2 in an architecture base graph G2, such that G ′ 2 is isomorphic to G1. G1 is a DAG extracted out fr...
