Abstract: The present invention relates to a layered semi-parallel LDPC decoder system having a single permutation network, and belongs to the field of decoder hardware design. The system comprises a layered decoding architecture of the single permutation network, a layered semi-parallel decoding architecture of the single permutation network, a pipeline design for layered semi-parallel decoding and a hardware framework of a layered semi-parallel LDPC decoder. The present invention removes a permutation network module between a check node and a variable node by modifying the cyclic shift value of each information block transferred from the variable node to the check node, i.e., the cyclic shift operation of the decoder can be completed through the single permutation network so as to reduce hardware resources of the decoder. A semi-parallel decoding structure is adopted, and meanwhile, a pipeline is added between half layers.

Abstract: A circuit structure for realizing circuit pin multiplexing, comprising an MCU module, a temperature sensing circuit and a functional module circuit. The output end of the temperature sensing circuit is connected with an enable signal interface of the MCU module, the output voltage of the temperature sensing circuit is always higher than the threshold voltage of the enable signal, and the MCU module is connected with the functional module circuit. The circuit structure of the present invention realizes the mutual influence of analog signal output and digital signal transmission by designing a temperature sensing output curve, and achieves multi-function multiplexing of a single pin, so that the output of the analog signal and the input of the digital signal can share the pins, it solves the problem of the limitation of the number of pins, and promotes the transmission of the signal and improves the cost performance of the circuit.

Abstract: An angle-dependent interference pigment based on transparent or translucent inorganic flake serving as a substrate is provided. The substrate is coated by coatings (A)+(B)+(C) and optionally coating (D), so as to form a “high-low-high” refractive index layered structure. The coatings (A) and (C) consist of metal oxides, silicate, aluminates and/or a mixture thereof. The coating (B) consist of silicon oxide, hydrous silicon oxide, aluminum oxide, hydrous aluminum oxide, magnesium oxide, hydrous magnesium oxide and/or a mixture thereof. The angle-dependent interference pigments have high color saturation in the transitional region and a significantly gradual color change in the color changing region. The present pigments can be used as colored coatings, including printing ink, or can be used in the preparation of plastics, glass, ceramics and the like. The pigment of the present invention is particularly used in the cosmetic industry which has a very high requirement on gradual color change.
