Abstract
A barrier-free atomic transfer method of multiword data is described. In the barrier-free method, a producer processor deconstructs an original parameter set of data into a deconstructed parameter set; and performs a series of single-copy-atomic writes to a series of single-copy-atomic locations. Each single-copy-atomic location in the series of single-copy-atomic locations comprises a portion of the deconstructed parameter set and a sequence number. A consumer processor can read the series of single-copy-atomic locations; verifies that the sequence number for each single-copy-atomic location in the series of single-copy-atomic locations is consistent (e.g., are all the same sequence number); and reconstructs the portions of deconstructed parameter set into the original parameter set.
