PIAGP CPU Card Selection Guide
The PCI Industrial Computer Manufacturers Group (PICMG) was established in 1994, setting its mission as defining specifications for industrial PCI/ISA passive backplane and CPU card interfaces. Various manufacturers have introduced a multitude of CPU cards for all kinds of applications, all based on the standards defined by PICMG, but the advances in high end AGP VGA cards has led to a bottleneck, and these standards have found severe performance limitations. Most CPU cards are equipped with a VGA function on board, but due to limitations in board sizes, and taking cost into account, these cards are unable to offer the graphic quality the user demands.

This now raises the issue of how to combine a PCI/ISA backplane with an AGP slot.

As one of the worlds pioneers in CPU mainboard technology, and after lengthy consultation with their clients, our supplier has developed a proprietary CPU card with AGP bus, designed to interface with their patented (patent pending) PCI/ISA/AGP passive backplane. This series of products are PIAGP (PCI, ISA and AGP) and cover the SAGP series of CPU cards and PCIAGP/PXAGP series passive backplanes.


PIAGP industrial CPU card and backplane.


Traditional PICMG PCI/ISA passive backplane solution with no AGP slot.

 The advantages of using this series of PIAGP cards are numerous:

1. Supports standard AGP version 2.0 slot on the PCIAGP/PXAGP series passive backplane

2. Compatible with all available AGP VGA cards PCIAGP/PXAGP backplane. Is also integrated with the PICMG PCI/ISA CPU card slot. Thus, traditional PICMG form factor CPU cards and our proprietary SAGP series CPU cards are supported.

3. When using an SAGP series CPU card, users can install a PISA-KIT01 PCI-to-ISA Conversion Module on the PCIAGP/PXAGP backplane to enable the ISA slots.

4. PCIAGP/PXAGP backplanes also provide an IDE RAID controller option. Using the backplane RAID controller, users can now assemble highly reliable industrial PC storage systems without any change to the CPU card configuration.
