摘要:
The present inventions are related to systems and methods for validating retry features in LDPC decoders and in systems incorporating LDPC decoders. For example, a data processing circuit is disclosed that includes a low density parity check decoder and is operable to correct errors in a data set. The data processing circuit includes at least one retry feature operable to assist in correcting the errors that are not corrected without the at least one retry feature. A retry validation circuit in the data processing circuit is operable to inject errors in the data set to trigger the at least one retry feature.

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.
