Patent DE-4038328-A1 (DE)
Inventor: MAHMUD SHABAZ
IPC: G06F5/06
Filed: 1990-12-01
Abstract: The invention relates to a method and a device for selectively reading out of or writing into predeterminable storage areas of a first-in/first-out memory. In these memories, the read/write process is sequential, that is to say reading-out occurs in the same order as writing-in. In these memory arrangements, reading-out or writing-in in any order is not possible. In many applications, however, it is advantageous to process or repeatedly process particular storage areas. The method according to the invention and the corresponding arrangement provide the possibility for selective processing of particular storage areas. In particular, a repeated processing of a storage area is made possible by simple means by marking the start address which forms the basis of the processing of this storage area.   <IMAGE>
