Abstract: An Integrated Messaging System which integrates mail from a plurality of mail servers handling messages of different media types such as text, voice, facsimile, video and image. The IMS maintains the in-basket for all mail systems, eliminating the need to collect each type of mail separately. Any terminal interface, telephone or computer workstation can be used to collect, generate and act upon a message of any media type. Further, from the preferred system, the user can request another file server and its associated terminals to perform messaging services. The system includes a variety traditional E-mail and voice mail functions which can be used for any message. The IMS also includes synchronization means which checks to see whether the mail count in each in-basket is the same to guarantee that the same mail items are in each file server in-basket. An integrated messaging protocol is used to pass information between the file servers.

Abstract: An address generator for an M-interleaved memory for accessing row or column elements of a matrix stored in a skewed matrix pattern includes an apparatus for circularly shifting the addresses for the i.sup.th row of a matrix by s(i-1) positions so that both row and column elements of the matrix can be accessed at the same access rate. In other words, apparatus is provided for circularly generating the sequences of appropriate memory addresses for the desired row or column elements so that either the row or column elements can be accessed at the memory system's maximum access rate. The apparatus includes a base register having an input connected to a first adder which adds an input value A to the contents in the base register for storing the output of the adder as a pointer to the beginning of the current row of the matrix in the memory to be accessed.
