| Popis: | The use of tonal displays in image analysis and interactive graphics has always dictated the use of expensive refresh memories for the display output device. This has involved the use of high speed digital drums, multiple head discs, and analog storage tubes. Recently, the introduction of very long shift registers has allowed the designer to consider their use for refresh memories. A prototype display using 1024 bit MOS static shift registers has been developed. It has been shown that a reasonable cost versus performance tradeoff can be obtained. The first efforts has resulted in a 128 × 128 × 4 bit (64k) memory; it is now in the process of being expanded to 256 × 256 × 8 bits (512k). This memory is cost competitive with digital disc memories and both cost and performance competitive with storage tube scan converters. |
