The core includes first and second members, a first group of one or more forms extending between the members, a second group of one or more forms extending between the members, and an isolating region that magnetically isolates the first group of forms from the second group of forms.

Abstract: An embodiment of a decoder for decoding a Low-Density Parity-Check encoded input data includes a serial processing unit operating in clock cycles to perform serial update of the layers in the code. Operations of the serial processing unit to produce output data for a current layer are pipelined with acquisition of input data for a next layer, whereby the current layer and the next layer may attempt to use soft output information common to both layers. The serial processing unit is configured for delaying acquisition of input data for the next layer over a number of idle clock cycles. Latency due to the idle clock cycles is minimized by selectively modifying the sequence of layers through the decoding process and the sequence of messages processed by a certain layer.
