HIGH PERFORMANCE READ-MODIFY-WRITE SYSTEM PROVIDING LINE-RATE MERGING OF DATAFRAME SEGMENTS IN HARDWARE

摘要

A method of merging data frames includes: receiving a first data frame having a plurality of sectors; receiving a second data frame having a plurality of sectors; generating a merged output data frame by merging, using a plurality of data paths including a plurality of multiplexers, sectors of the second data frame with sectors of the first data frame; and performing an error check on at least one check-data frame having sectors corresponding to those in the first data frame or the second data frame, where at least some of the sectors in the check-data frame are transmitted on a subset of the plurality of data paths that transmits sectors of the merged output data frame, and where the error check verifies the merged output data frame.

1. A method of merging data frames, the method comprising:
receiving a first data frame comprising a plurality of sectors; receiving a second data frame comprising a plurality of sectors; generating a merged output data frame by merging, using a plurality of data paths comprising a plurality of multiplexers, sectors of the second data frame with sectors of the first data frame; and performing an error check on at least one check-data frame that comprises sectors corresponding to those in the first data frame or the second data frame, wherein at least some of the sectors in the check-data frame are transmitted on a subset of the plurality of data paths that transmits sectors of the merged output data frame, and wherein the error check verifies the merged output data frame.
