PCI communication card with intelligent processor

17 October 2007 Computer/Embedded Technology

Advantech's PCI-1625U 8-port intelligent RS232 universal PCI communication card has an onboard DSP processor, which can carry signals by itself, reducing host CPU usage. The PCI-1625U has a universal PCI connector that is compatible with both the newer 3,3 V PCI bus and the traditional 5 V PCI bus.

An intelligent onboard processor takes a significant load off the host CPU (only 18% CPU usage at 921,6 K baud rate), and provides a large onboard buffer for high performance communications (90 Kbyte per second throughput at 921,6 K baud rate). With these advantages, users can reduce CPU usage and the occurrence of CPU errors.

Within its onboard processor and 1 MB embedded SRAM, signals and data can be transmitted and saved immediately when passing through the serial ports. These features make this unit capable of high performance processing to meet high-speed and data intensive communication applications.
