Abstract
A dependency controller and method for overlapping memory access operations whose addresses carry an identifier, in which controller the addresses which have not yet been processed are stored under the identifier and a comparison of each new address with all the stored addresses is used to produce and store a dependency vector whose bits are allocated to the identifiers and are deleted by the identifier when memory access has been completed.
