Message preprocessing operations indicated by an associated descriptor read and descriptors belonging to a category of preprocessing descriptors and a category of instruction descriptors

Abstract

A method for the reception and preprocessing of digital messages, with a view to their use by a handling processor. The method associates a tag identifying each message capable of being received with a descriptor of preprocessing operations to be applied to the message. The tag of certain messages is associated with a sequence of descriptors of instructions capable of being run. The descriptor is stored in a memory at an address calculated with the aid of the tag of the associated message. Upon reception of a message, the tag of the received message is read, the address of the descriptor is determined with the aid of the tag, the descriptor is read at the address thus calculated, and the instruction sequence associated with the tag of the message is run if the descriptor is of the instruction type.
