1 thought on “What is LPC?”

  1. In principle, the LPC is a parameter of a channel incentive and transfer function by analyzing the tone waveform. The encoding of sound waveforms is actually transformed into encoding these parameters, which greatly reduces the amount of sound data. Use LPC analysis parameters on the receiving end to reconstruct the voice through the synthesizer. The synthesizer is actually a discrete line -changing filter over time. It represents the sound generation system model of the person. Time variable linear filters are used as predictors and used as synthetic. When analyzing the sound wave shape, it is mainly used as a predictor. When synthetic phonetic sounds are used as a phonetic modeling model. With the changes of the phrase, the periodic parameters and incentive conditions of the model are suitable for new requirements.
    It, in order to connect the ISA expansion slot, adapter, ROM BIOS chip, Super I/O and other interfaces, the South Bridge chip must retain an ISA Bus and connect the Super I/O chip to control the traditional peripheral devices. The traditional ISA Bus rate is about 7.159 ~ 8.33MHz, and the theoretical peak transmission value is 16MB/s, but the electrical characteristics and signal definition methods of ISA Bus are very different from the traditional PCI bus. Waste the needle to do it, and the line design of the motherboard is also complicated.
    INTEL’s PC interface, separate the address/data separation decoding of the previous ISA Bus to the decoding method shared by the address/data signal line similar to PCI. Synchronous driving, although the improved LPC interface maintains a maximum transmission value of 16MB/s, the number of signal foot positions required is greatly reduced by 25 to 30. The Super I/O chip and Flash chip designed with the LPC interface can enjoy the feet The benefits of decreased digits and a decreased volume can also be simplified by the mother design, which is the reason for named LPC -Low Pin Count
