Abstract: A low density parity check (LDPC) decoder initializing variable nodes with a value of a codeword and outputting the updated variable nodes as decoded messages with reference to an irregular parity check matrix. The LDPC decoder includes a plurality of unit logic circuits operating in a single mode in which all the unit logic circuits update one variable node group including at least one variable node, or a multi-mode in which each of the unit logic circuits updates a plurality of variable node groups in parallel by updating different variable nodes, and a mode controller controlling the plurality of unit logic circuits to update a high-degree variable node group having a degree greater than a threshold degree among the variable node groups in the single mode, and update a low-degree variable node group having a degree less than or equal to the threshold degree among the variable node groups in the multi-mode.

Abstract: A breadcrumb coating machine includes a breadcrumb coating unit for spreading and fixing breadcrumbs on the front and rear surfaces of pork. The breadcrumb coating unit has an octagonal frame formed in a regular octagon shape and disposed on an upper surface of a base; a turntable having breadcrumbs dispersed over the surface thereof and configured to rotate on the upper surface of the octagonal frame; first and second scattering units configured to draw the breadcrumbs dispersed on the surface of the turntable and to scatter the same over the upper surface of the pork; and a pressing plate disposed at an interval from the first and second scattering units in a clockwise direction to press the upper surface of the pork, while adjusting a pressure by using a cylinder.

Abstract: The present invention provides a turntable-type breadcrumb coating machine characterized by comprising: a breadcrumb coating unit for spreading and fixing breadcrumbs on the front and rear surfaces of pork; an introduction unit for coating the pork with an egg wash and introducing the same towards the breadcrumb coating unit; and a discharge unit for discharging the pork, which has been coated with breadcrumbs through the breadcrumb coating unit, wherein the breadcrumb coating unit comprises: a turntable, which has breadcrumbs dispersed on the surface thereof, and which is provided to rotate on the upper surface of a base; first and second scattering units for drawing the breadcrumbs, which are dispersed on the surface of the turntable, and scattering the same over the upper surface of the pork; a first pressing roll installed at an interval from the first and second scattering units in the clockwise direction such that the same can press the upper surface of the pork while the pressurizing force being adjust
