Abstract: A method, medium, and apparatus to effectively handle an interrupt in a reconfigurable array. In the method, the reconfigurable array pauses execution of an operation when an interrupt request occurs, and after storing register values of a register to be used for handling the interrupt request, an interrupt service is performed by select processing units of the reconfigurable array in response to the interrupt request. Upon completion of the interrupt service, the register values are restored, and the reconfigurable array resumes execution of the operation.

Abstract: A method, medium and apparatus for storing and restoring a register context for a fast context switching between tasks is disclosed. The method, medium and apparatus may improve overall operating speed of a system by increasing the speed of context switching. The method may include adding an update code for updating information of live registers to a task file that includes a code of a task to perform a specified function, converting the task file having the update code added thereto into a run file, updating the information of the live registers with the update code during running of the task using the run file, and storing a live register context according to the updated information of the registers.

Abstract: A method of reducing a code size of a program by controlling a control flow of the program using software in a computer system is disclosed.

Abstract: A channel estimation apparatus for WCDMA mobile communication terminal is disclosed. The channel estimation apparatus includes a moving average filter for calculating the average value of pilot signals; an interpolator for computing a tentative estimation value of channel variation by using linear interpolation algorithms based on the average value of pilot signal; a channel compensator for compensating a channel variable of the data signal delayed in a predetermined time based on the tentative estimation value of channel variation; a decision block unit for tentatively determining data signal based on the compensated data signals; a raw channel estimator for computing a raw channel estimation value based on the output signal of the decision block unit and the data signal delayed; and a non-linear filter for computing a final channel estimation value of channel variation based on the tentative estimation value of channel variation and the raw channel estimation value.
