| 摘要 |
An audio coding device for coding input signals of a plurality of channels over a plurality of time sections is disclosed. The device includes a parallel transform unit, which can store input signals of two or more channels and also input signals of two or more time sections in one SIMD variable and collectively perform transform on the input signals of the two or more channels and the input signals of the two or more time sections by using SIMD processor. An audio decoding device includes a parallel in verse transform unit, which can store transformed signals of two or more channels in one SIMD variable and collectively perform inverse transform with respect to the two or more channels by using SIMD processor.
