    摘要: A signal arrival direction deducing device capable of deducing the signal arrival direction even when a correlation matrix between input signals and noise correlation matrix are singular. A state is observed in which only noise is present and a state is observed in which a sound whose arrival direction is to be deduced. A short time Fourier transform is performed. Correlation matrix and an input signal correlation matrix are used to compute proper eigenvalues/proper eigenvectors and improper eigenvectors of the noise correlation matrix with respect to the input signal correlation matrix. A matrix for determining the complementary space component of the signal partial space is computed from the proper eigenvectors and the improper eigenvectors. An arrival direction search is made for the sound arrival direction using the matrix for determining the complementary space component of the signal partial space.

    摘要: A high-sped block is formed by generating and connecting a new basic block (contains an intermediate code obtained by performing variable replacing processing to a path replacement target variable of the intermediate code on a hot path of an original partial program and contains a branching intermediate code where a branching instruction on the hot path is converted so as to execute the hot path), and a basic block with an intermediate code for restoring value of path guarantee variable among the path replacement target variables to a value of an original variable. When an execution result of a conditional branching intermediate code is true, the speeding up of the original program is achieved through executing the basic block, and performing dependency analysis and dependency generation between the intermediate codes in the high-speed block and scheduling of the instructions.
