Abstract:

A cache memory system in a data processor that has a main memory and a processing unit, the cache memory system including a virtually addressed storage cache. This virtually addressed storage cache is connected to the main memory for storing in storage cache locations preselected portions of data from the main memory. Each cache location includes a valid indicator to indicate the data in the cache location is current. A translation buffers is coupled to the storage cache, and translates a virtual address to a physical address. The backmap is coupled to the storage cache and the translation buffer, and invalidates data in the storage cache by generating an invalidate index to the cache location at which a valid indicator is to be cleared only when data in the storage cache is to be invalidated. The cache memory system includes at least one lockout register for storing addresses for data which may exist in more than one storage location. The backmap invalidates all copies of the data in the storage cache after every reference to data in the storage cache using an address in the lockout register.

Abstract:

A rotary table assembly apparatus for stuffing a snailed endless ribbon into a ribbon cartridge comprises a rotary table, a mounting plate affixed to the table for mounting and positioning a bottom housing of a ribbon cartridge, a loop tray affixed to the front portion of the mounting plate for holding a snailed loop while it is being stuffed into the ribbon cartridge, adjustable slide panels mounted on the loop tray to create narrow slits with a pin to hold the ribbon upright as it passes through the slits into the ribbon cartridge and to prevent more than one layer of ribbon from passing from the loop tray into the cartridge, and a cover for keeping the ribbon from jumping out of the loop tray as the ribbon is being fed into the cartridge. A method of stuffing an endless looped fabric ribbon into a ribbon cartridge which is used with a typewriter or a printer, comprises the steps of placing a ribbon which has been wound into a snailed loop into a loop tray, closing the top of the tray by placing a cover over it so that the ribbon cannot jump out of the tray while it is being rewound and stuffed into the ribbon cartridge, pressing a cartridge cover over the cartridge housing, and rewinding the ribbon to draw it from the loop tray and stuff it into the cartridge.
