System and method for expeditious transfer of data from source to destination in error corrected manner

摘要

A system and method for expeditious transfer of data from a source device to a destination device in error corrected manner are provided. The system and method avoid the substantial delay in utilizing an intermediate buffer, determining error, and remediating the detected errors before even initializing a transfer of an input data from the source device to the destination device. Upon completion of error correction, only those portions corrected are retransmitted to the destination memory rather than the complete corrected input data. A by-pass section is provided for copying input data to the destination memory with at least a degree of parallelism with the error detection of the input data delivered to a parallel buffer coupled with the correction section by a splitter section.

1. A method for expeditious transfer of data from source to destination in error corrected manner, comprising:
establishing a destination memory; establishing a transfer controller to receive input data for delivery to said destination memory, the input data having a predetermined verification feature associated therewith; actuating said transfer controller to deliver the input data substantially as received to said destination memory; actuating said transfer controller to monitor the input data for error in portions thereof based on said predetermined verification feature, said transfer controller generating a corrected portion for each portion of the input data detected to contain error; and, delivering each said corrected portion to said destination memory to correct according to said corrected portion a corresponding portion of the input data previously delivered to said destination memory.
