Abstract
Various embodiments of the present invention provide systems and methods for stochastic stream decoding of binary LDPC codes. For example, a data decoder circuit is discussed that includes a number of variable nodes and check nodes, with serial connections between the variable nodes and the check nodes. The variable nodes are each operable to perform a real-valued computation of a variable node to check node message for each neighboring check node. The check nodes are operable to perform a real-valued computation of a check node to variable node message for each neighboring variable node. The messages are passed iteratively between the variable nodes and the check nodes.
