  • Fast loop iteration and bitstream formatting method for MPEG audio encoding
    Patent number: 6678648
    Abstract: In an MPEG audio encoder, a sign and an absolute value calculation are performed outside of the quantization inner loop, thereby reducing redundant calculations. The stored sign and absolute values can also be used in the frame packing block, also increasing processing efficiency. Thus, the present invention improves the performance of an MPEG audio encoder.
