The flexible image acquisition interface handles any clock/data relationship at up to 20 MHz pixel rates with its standard RS422 interface, or at up to 40 MHz pixel rates with an optional LVDS (EIA644) interface. On-board real-time image re-sequencing for multi-tap digital cameras significantly reduces host CPU burden thereby giving the host more time to process and analyze image data.
The parallel digital video acquisition board provides a fast transfer of video data to host PC memory. With 4MB of high-speed, SGRAM memory, sustained transfer speeds of up to 120 MB/second are achievable. This product is capable of bus mastering image data directly to the host PC memory as lines become available or as full 8- or 16-bit images in either normal or 4:2:2 image format. In addition, through the 4:2:2 image format the PC-DIG is able to deliver non-destructive overlay on live images with 0% load on the host CPU. The scatter-gather feature enables automated image transfers which further reduces CPU overhead and leaves much needed processing cycles for demanding continuous inspection applications.
