摘要：A prioritized buffer for the Medium Access Control (MAC) layer for multimedia

applications, in particular wireless Asynchronous Transfer Mode (ATM) in which

reservation based TDMA is performed on the basis of control data frames (CDFs), is

formed by an addressable memory system which is divided into sequential equal-sized

pages for storing respective data packets or ATM cells having the same number of bytes.

The memory system includes a tag register for storing tags associated with the

respective pages, each tag indicating whether the associated page is empty or full, a

shadow register for storing conflict-free updates from the tag register, and a page

register for storing pointers to the lowest free or unoccupied page. Sequential buffer

addresses of memory locations in the memory system, which control sequential writing

into the buffer of bytes contained in data packets, are generated from summing a first

address component responsive to the contents of the page register and a second

address component which is a byte count of a current packet being received from a

stream data source. A succession of byte addresses is produced which jumps over

addresses within pages which are full, thereby bypassing and avoiding overwriting pages

which are full.
