Paper Abstract

Currently, most portable digital imaging systems use standard 3.5 inch floppies for storage of images and data. Driven by an increasing demand for smaller, lighter, lower power devices, the space restrictions for a digital storage device have become more severe. One solution is to provide a separate device containing the floppy drive, with its own power source, connected to the imaging system with external cables. A better method is the use of PCMCIA memory cards. PCMCIA (Personal Computer Memory Card International Association) memory cards have many advantages over floppy drives. They are smaller, more rugged, faster, and require less power. PCMCIA memory cards can be formatted to accept DOS files, making it easy to move files to a PC for archiving and image processing. Including a PCMCIA socket and controller circuitry in an imaging system provides a convenient upgrade path for future capabilities. The problems associated with adding PCMCIA memory card storage to a portable imaging system are formidable, however. There is little or no off-the-shelf software to support these cards in an embedded system. Since it is a relatively new technology, there is very little public, practical knowledge to guide the embedded systems designer. The PCMCIA standards are lengthy and complicated, and still changing. Memory card technology is changing and card prices are still much higher than for floppies. These and other issues were encountered on a recent development project at Inframetrics. This paper discusses how these issues were addressed and assesses where PCMCIA is headed.
