    Abstract: In a signal processing method to compress digital audio data by a block floating process, digital signal encoding/decoding apparatuses prevent deterioration of sound quality of the digital audio signal and improve the compression ratio of the digital audio signal when the digital audio signal is converted on a frequency axis per predetermined time frame, and data on the frequency axis is then divided into a plurality of blocks to be recorded, otherwise, bits are allocated per block to compress the digital audio signal for minimizing transmitted parameters. Also, encoding/decoding methods are provided to enable highly efficient encoding/decoding without recording or transmitting word length, allowing one to obtain a high-quality audio signal by allocating bits conventionally held by the word length to hold quantization data of a spectrum signal.

    Abstract: Digital data formatting/deformatting circuits perform digital data formatting/deformatting operations separately from a digital signal processor to reduce the required time and power consumption in formatting and deformatting digital data. In the formatting operation, the data to be formatted are arranged in a line and then outputted in the unit of a desired number of bits. In the deformatting operation, the formatted data are arranged in a line and then outputted in the unit of the original number of bits.

    Abstract translation: 数字数据格式化/去格式化电路与数字信号处理器分开执行数字数据格式化/去格式化操作,以减少格式化和格式化数字数据所需的时间和功耗。 在格式化操作中,要格式化的数据被排列成一行,然后以期望的位数为单位输出。 在去格式化操作中,将格式化数据排列成一行,然后以原始位数为单位输出。
