Abstract: PURPOSE: An apparatus for cancelling wideband acoustic echo and a method thereof are provided to minimize power consumption of a normalized least mean square (NLMS) device and to perform rapid recovery of a system. CONSTITUTION: An operation unit (130) calculates a threshold value and performance index of a filter coefficient. When the filter coefficient is smaller than the threshold value, a register (140) stores position information of data. When the performance index is lower than a predetermined convergence index after the performance index is compared with the convergence index by using a judgment unit, an index counter unit (150) increases a feedback counter value. When the feedback counter value corresponds to a predetermined recovery reference value, a recovery unit (160) recovers the feedback counter value to a filter coefficient value.

Abstract: A direct memory access controller (DMAC) for improving data transmission efficiency in multi-media over internet protocol (MMoIP) and a method therefor are provided. The DMAC requests and obtains a bus control right by determining that a DMA request signal is generated not only when a DMA request signal of a module for processing data in MMoIP is received but also when an operation of a timer operating during a predetermined period set considering periodicity of data in MMoIP is completed. Thus, the time taken to request a bus control right in a conventional DMAC can be reduced, thereby improving data transmission efficiency in MMoIP.

CONSTITUTION: A logic equation of a circuit is input for measuring a power consumption, a logic diagram is constructed based on the logic equation, and the total number of internal nodes and output nodes in the circuit are counted(101, 102). Obtained is a probability that an input node of a gate element within a circuit is 1, and the transition density of the input node is detected(103, 104). It is determined whether obtained is a probability that an output node of a gate element within a circuit is 1, and if the probability is not obtained, the probability is calculated based on a BDD(Binary Decision Diagram) method(105, 106). An input transition condition for making a transition of an output of a gate element is detected(107). The output transition density of a gate element is calculated by using an occurrence probability of an input transition condition and a probability of an input node is 1(108).
