Abstract
Abstract The overlay of information from the computer memory to a peripheral memory and its return to the computer memory are facilitated by a unique format for original and copy descriptors. The copy descriptors have a first field that designates either a base address or the location of its original, and a second field that designates an index. The original descriptors have a field that designates the base address. The copy descriptors are automatically generated from their originals. When a copy descriptor is retrieved, the first and second fields are added to form the absolute address if the first field is the base address. If the first field is an original descriptor location, the base address of the original descriptor and the index of the copy descriptor are added to form the absolute address. Upon overlay, the copy descriptors to be updated are sensed by comparing their base value with the base value of the array to be overlaid. They are updated by substituting the original descriptor location for the base address and the original descriptors are updated by substituting the peripheral memory address for the base address. Upon return of the overlaid information to the computer memory, only the original descriptor must be updated.

A method for updating address values of information processed by a digital computer that functions with a peripheral memory, the computer having an addressable computer memory, the method comprising the steps of: generating and storing copy descriptors and original descriptors referencing information stored in groups of memory cells forming arrays in the computer memory, the copy descriptors including a first field designating either the base address value of an array in the computer memory or the storage location of an original descriptor of the array in the source and a second field designating the index value of a cell in the array from the base address value, the original descriptors including a first field designating the base address value of an array in the computer memory or an address value in the peripheral memory where the information from the array is stored and a second field designating the length of the array; returning overlaid information to an array of the computer memory from the peripheral memory; and substituting for the peripheral memory address value in the first field of the original descriptor referencing said information the base address value of the array to which the information is returned.

A method for producing copies of original descriptors referencing information stored in a computer memory of a digital computer that functions with a peripheral memory; the computer having a source of descriptors to be copied; the source including copy descriptors having a first field designating a base address or the location of its original descriptor in the source and a second field designating an index value and original descriptOrs having a first field designating a base address or a peripheral memory address and a second field designating the nature of the first field, the method comprising the steps of: retrieving from the source the descriptor to be copied; substituting for the peripheral memory address in the first field of the retrieved descriptor the location of such descriptor in the source when a peripheral memory address is present in the first field of said retrieved descriptor, thereby forming a copy descriptor; and placing the copy descriptor in the source.
