    Abstract: Interleaving/de-interleaving may be performed by transferring multi-byte data blocks to be interleaved or de-interleaved into a set of memory banks on a column-by-column basis, transferring the data blocks to a data memory on a row-by-row basis, transferring the data blocks back to the memory banks on a row-by-row basis, using a set of shifted addresses that may cause cyclic shifting of the row orders, and transferring the interleaved or de-interleaved data blocks out of the memory banks on a column-by-column basis. The roles of rows and columns may, equivalently, be reversed.

    Abstract: The present invention provides an integrated display system for multi-media workstations wherein graphics image and video data are merged in a single frame buffer. The integrated display system employs 3-port VRAMs with a first serial access port for display data output, and a random access port for graphics data, a second serial access for video data input. The display system includes a single frame buffer memory system for a multi-media workstation which operates compatibly with display systems and logic designed for dual frame buffer systems and it uses the 3-port VRAM in combination with a means incorporating improved input locking, video update or refresh, and encoded video data input stream.

    Abstract: A laser imaging system is disclosed which provides the versatility of wide field digital imaging with enhanced spatial resolution and light gathering efficiency. The system will scan targets of any size, dependent only upon the data retrieval and storage limitation of the computer support system, for forward light loss densitometry images as well as fluorescent and forward scatter images. The system is easily adaptable for rare event detection and tracking. The laser system will provide image capture of an entire target within 10 to 60 seconds and controls the scan of the laser beam in three-dimensional pattern and speed. The beam may be repositioned to any one of 16 million locations on a target within an accuracy of +/-0.5 um. Finally, the imaging system of the present invention utilizes a novel optical fiber based detector assembly having NA values of 0.58-0.95 and filters having less than 15% loss at emission wavelengths. Thus, the imaging system of the present invention can capture from 14% to 32% of total fluorescence emission.
