Various embodiments of the present invention provide systems and methods for data processing. For example, a method for data processing is disclosed that includes: receiving a data input having at least a first local chunk and a second local chunk, the data input also being defined as having at least a first global chunk and a second global chunk; rearranging an order of the first local chunk and the second local chunk to yield a locally interleaved data set; storing the locally interleaved data set to a first memory, such that the first global chunk is stored to a first memory space, and the second global chunk is stored to a second memory space; accessing the locally interleaved data set from the first memory; and storing the locally interleaved data set to a second memory. The first global chunk is stored to a third memory space defined at least in part based on the first memory space, and the second global chunk is stored to a fourth memory space defined at least in part based on the second memory space.

Various embodiments of the present invention provide systems and methods for a data processing system with thermal control. For example, a data processing system with thermal control is disclosed that includes a number of data processors and a scheduler, which is operable to determine the power consumption of the data processors and to switch the data processing system from a first mode to a second mode and from the second mode to a third mode. The data processing system consumes less power in the third mode than in the first mode. The second mode prepares the data processing system to enter the third mode.

In a communications system that demultiplexes user data words into multiple sub-words for encoding and decoding within different subword-processing paths, the minimum distance between bit errors in an extrinsic codeword can be increased by having corresponding subword encoders/decoders in the different subword-processing paths perform subword encoding/decoding with different encoder/decoder matrices.

摘要:
In one embodiment, an LDPC decoder has a plurality of check-node units (CNUs) and a controller. Initially, the CNUs generate check-node messages based on an initial offset value selected by the controller. If the decoder converges on a trapping set, then the controller selects new offset values for missatisfied check nodes (MSCs), the locations of which are approximated, and/or unsatisfied check nodes (USCs). In particular, offset values are selected such that (i) the messages corresponding to the MSCs are decreased relative to the messages that would be generated using the initial offset value and/or (ii) the messages corresponding to the USCs are increased relative to the messages that would be generated using the initial offset value. Decoding is then continued for a specified number of iterations to break the trapping set. In other embodiments, the controller selects scaling factors rather than, or in addition to, offset values.
