Abstract: An apparatus for providing a data integrity field implementation in a data processing system includes a controller operative to interface between a host device and a destination device in the data processing system for transferring at least one data block therebetween. The data processing system further includes an error detection module associated with the controller. The error detection module is operative to determine a probability of an error occurrence based at least in part on a measured current error rate for the data processing system. The controller is operative to implement an error correction methodology which is selectively adaptable as a function of the probability of an error occurrence.

Abstract: A memory management apparatus includes a first controller adapted to receive an input data sequence including one or more data frames and operative: to separate each of the data frames into a payload data portion and a header portion; to store the payload data portion in at least one available memory location in a physical storage space; and to store in a logical storage space the header portion along with at least one associated index indicating where in the physical storage space the corresponding payload data portion resides. The apparatus further includes a second controller operative, as a function of a data read request, to access the physical storage space using the header portion and associated index from the logical storage space to retrieve the corresponding payload data portion and to combine the header portion with the payload data portion to generate a response to the data read request.
