- a layered data decoder circuit;
- and
- a non-layered data decoder circuit.
1 more element
A data processing system, the data processing system comprising:
- a dual pass data decoder circuit operable to:
- access a data set from a memory for a first pass through the dual pass data decoder circuit;
- update a check node to variable node message based at least in part on the data set during the first pass;
- re-access the data set from the memory for a second pass through the dual pass data decoder circuit;
- and
- apply the check node to variable node message during the second pass to yield an output.
3 more elements
A method for data processing, the method comprising:
- providing a data decoder circuit selectably configurable to operate as one of:
- a layered data decoder circuit;
- and
- a non-layered data decoder circuit;
- configuring the data decoder circuit to operate as a layered data decoder circuit;
- applying a layered data decoding algorithm to a data set using the layered data decoder circuit;
