    摘要： An apparatus and method for tracing memory access information of a user program while ensuring a normal operation of the user program. An access permission about a memory region may be set to trace the memory access information. An instruction of the user program encounters a page fault according to the set access permission. If the page fault occurs, memory access information is stored based on the page fault, and apparatus executes an instruction causing the page fault while in a supervisor mode.

    摘要： An audio quality enhancing apparatus and method is provided in which a microphone array has a non-uniform configuration and thus a beam pattern of a desired direction is obtained in a wide range of frequencies including higher frequency bands and lower frequency bands even when the microphone array is relatively small. The audio quality enhancing apparatus includes at least three microphones which are disposed in a non-uniform configuration, a frequency conversion unit configured to transform acoustic signals input from the at least three microphones to acoustic signals of frequency domain; a band division and merging unit configured to divide frequencies of the transformed acoustic signals into bands based on intervals between the at least three microphones and to merge the acoustic signals in the frequency domain into signals of two channels based on the divided frequency bands; and a two channel beamforming unit configured to reduce noise of signals including input from a direction other than the direction of a target sound by performing beamforming on the signals of the two channels and to output the noise-reduced signals.

    摘要： An apparatus and method for dynamically analyzing a program are provided. The apparatus and method help minimize overhead in tracing the execution of the program without substantially affecting the operation of the program at run time. The method includes storing an environment value before execution of a function of a main page by storing a first instruction of the function in a temporary page before execution of the first instruction. The method also includes inserting a break instruction at an address of the first instruction in the main page, executing the break instruction, and storing an environment value after execution of the function by executing a break instruction of the temporary page.

    摘要： A method of detection of erroneous memory usage is provided. The method includes starting a computer and executing a program and a monitoring tool to collect calls to a memory during execution of the program, detecting a call to the memory using the monitoring tool, extracting lines of code which request access to a memory address via the call to the memory, detecting a set of variables to which access is granted via the call to the memory, extracting, after execution of the predetermined program, the set of variables for each of the lines of code, detecting erroneous memory usage by matching the extracted lines of code with the set of variables, and determining the call as erroneous upon access being granted to the memory corresponding to the set of variables during execution of the predetermined program when access is not possible during the execution of the program.
