Interleaving Imaging Device Controller With Multi-Use Circuitry

US Patent:
2003010, Jun 5, 2003
Filed:
Oct 15, 2002
Appl. No.:
10/272442
Inventors:
Keiichiro Hyodo - Los Gatos CA, US
Peter Johnson - San Mateo CA, US
Allan Hessenflow - Los Gatos CA, US
International Classification:
G06F003/12, G06F013/00, G06F015/00
US Classification:
358/001130, 358/001150
Abstract:
An imaging device with an improved controller is disclosed wherein the controller eliminates duplicated circuitry and provides multi user circuitry that efficiently replaces multiple dedicated circuit blocks. In one aspect, duplicated same-function circuit blocks are replaced with a switch controlled by an alignment control signal to operate as a multiplexer or demultiplexer. In another aspect, multiple different-function circuit blocks which generally have no temporal overlap of their active operation are replaced with a programmable logic device that is reconfigured dynamically to perform some subset of the different functions on an as-needed basis.
