An intelligent notification device is provided. The intelligent notification device is adapted to communicate with at least one electronic device. The intelligent notification device includes a detecting device and a controller. The detecting device detects a status parameter of at least one user and an enviromental parameter of the electronic device. The controller is electrically connected to the detecting device to control the electronic device to notify one of a plurality of events in an event schedule according to the event schedule and to dynamically adjust a time sequency of the events in the event schedule according to at least one of the enviromental parameter and the status parameter. An intelligent notification method is further provided.

Intelligent notification device and intelligent notification method

The invention describes a simple and efficient codeword degrouping algorithm which can be applied in an MPEG audio decoder, in which a codeword is degrouped into three samples. According to the proposed algorithm, the division and modulo computations applied in the original degrouping method can be fully substituted into the addition and subtraction computations by using the mode selection and iterative decompositions, and thus largely reduces the overhead and complexity for the decoder. Also, an efficient architecture for the proposed algorithm includes one special adder, two subtractors, and two adders. The architecture generates the quotient and remainder simultaneously with fix-rate throughput.

Method of degrouping a codeword in MPEG-II audio decoding by iterative addition and subtraction

An MPEG-II audio decoder with a synthesis subband filter includes a fast IMDCT (Inverse Modified Discrete Cosine Transform) module and an IPQMF (Inverse Pseudo Quadrature Mirror Filter) module. The fast IMDCT module involves a butterfly stage of input subband samples which requires only about &frac14; the amount of multiplier-accumulate computation of the ISO suggested method. The IPQMF module involves an efficient memory configuration which requires only half size of the standard synthesis subband filter bank.

A hardware structure for inverse quantization and multichannel processing in MPEG-2 audio decoding is provided, which includes 5 groups of first-in-first-out (abbreviated as FIFO) registers, each group of which has 3 FIFO registers and are connected in series; a multiplier capable for receiving an internal data processing feedback from the last FIFO group of FIFO registers; a single register; a first adder/subtractor capable for receiving a feedback from the first group of FIFO registers and its output being fed to the first group of FIFO registers; a second adder/subtractor capable for receiving a feedback from a second group of FIFO registers. The second group of FIFO registers stores an output from the second adder/subtractor or an output from the first group of FIFO registers; a third group of FIFO registers stores an output from the single register or an output from the second group of FIFO registers; a fourth group of FIFO registers stores an output from the third group of FIFO registers; and so on. The single register output the calculated value of the multiplier as an output of the structure or to at least one of the first second adder/subtractor, second adder/subtractor and the third group of FIFO registers.
