PCVisionplus® is a new high performance analog frame grabber that digitizes monochrome analog video to 8 or 12 bits at sample frequencies up to 53 Mhz. PCVisionplus supports broadcast standard timing (RS170, CCIR), progressive scan and nonstandard (variable scan) timing, as well as two monochrome cameras.

Since the high data transfer rate of the PCI-bus eliminates the need for on-board processing or display circuitry, image display and processing are controlled by host computer resources. Linear format image memory permits multi-size image acquisitions. Image memory itself behaves as a temporary buffer between the camera interface and the host PCI-bus system. PCVisionplus incorporates a hardware "scatter gather" table for highly efficient, fully automated image transfers from image memory. This feature frees the host CPU allowing it to perform processing during bus master transfers rather than it having to control the transfer operation itself. The bus master controller also has multiple frame ping-pong source and destination capabilities. Applications can program the PCVisionplus to establish processing time.

PCVisionplus can transmit, through the bus mastering process, image data directly to destination memory within the PCI-bus system, such as system or VGA memory. Transfer rates up to 133MB/sec can be sustained depending upon the host capabilities. This means that Images can be transferred to host memory in a fraction of the time that they are acquired. By minimizing the PCI-bus transfer time and CPU overhead, more bandwidth is available for processing or for use by other system resources.
