Although SIMD instructions are effective for many digital signal processing applications, current compilers cannot take full advantage of SIMD instructions. One factor inhibiting SIMD code generation is control flow structure; the target scope of SIMD code generation is currently limited to single basic block or loop that consists of single basic block. SIMD instructions cannot be mapped typically...
This paper proposes a multi-objective genetic programming (MOGP) for automatic construction of feature extraction programs (FEPs). The proposed method is modified from a well known non-dominated sorting evolutionary algorithm, i.e., NSGA-II. The key differences of the method are related with redundancies in program representation. We apply redundancy regulations in three main processes of the MOGP,...
This paper propose a new recombination method, named redundancy-removed recombination, for linear genetic programming based image recognition program synthesis. The redundancy-removed recombination produces an offspring (by conventional crossover or mutation), and then adopts a canonical transformation to convert the offspring into its canonical form, in which it can be verified whether it has been...
Recently, evolutionary computation (EC) has been adopted to search for effective feature extraction programs for given image recognition problems. For this approach, feature extraction programs are constructed from a set of primitive operations (POs), which are usually general image processing and pattern recognition operations. In this paper, we focus on an approach based on a variation of linear...
This paper proposes a low power VLIW processor generation method by automatically extracting non-redundant activation conditions of pipeline registers for clock gating. It is important for the best power reduction by clock gating to create control signals that can completely shut off redundant clock supplies for registers. In order to generate the control signals automatically, the proposed method...
