Data transfer interface module

摘要

A data transfer interface module comprises a storage zone constituted by a plurality of locations referenced by addresses provided by an address generator and serving to acquire a set of data items constituting a block of a size that may be variable, which data items are stored successively in the plurality locations; a control signal COM via control circuit and an acquisition and recording circuit to enable address generation and also loading in the storage zone, the same control circuit in association with a read and transmission circuit then enabling the data to be transmitted, with the data items being extracted one by one from the locations, such that the first item to be transmitted is the last item to have been recorded; and a monitor circuit controlled by the address generator and serving to verify that the number Do of data items transmitted is equal to the number Di of data items acquired and to provide a status word ST which can be read to provide information about proper transmission.
