P0CC1-5SP Abaco Systems PMC Carrier Card

The Abaco Systems / Radstone P0CC1 Series PMC Carrier Cards can accommodate 2 PMC's and is compatible with Radstone's PPzero technology. Up to (4) P0CC1 carrier cards can be used with one Single Board Computer, allowing access to a maximum of (9) PMC's from the SBC. This offers easy system upgrade at low incremental cost, using Radstone's proven range of SBC's and PMC's designed for Networking, Graphics, Signal Processing, and other standard or customized I/O functions.

The PPzero concept realizes PCI extension over the P0 connector of Radstone's standard range of 6U VME Single Board Computers. PPzero can be used to achieve straightforward PCI extension to P0CC1 carrier cards in order to access additional PMC's, or for high bandwidth peer multiprocessing over PCI.

Within the PPzero implementation, the P0CC1 is attached via its P0 connector to a host PCI infrastructure. This is provided by an SBC fitted with a PMCPCI (a half size PMC adapter card), which links the SBCs internal PCI to a P0 PCI backplane. The SBC is plugged into the master slot of the P0BP range of P0 PCI backplanes, the P0CC1s being plugged into any of the other available slots on the same PCI backplane. The P0CC1 cards and the PMCPCI adapters both employ PCI-to-PCI bridges to create secondary PCI busses, which support concurrent transactions with their primary PCI busses. These bridge chips also allow buffering of PCI data and addresses for posted memory write operations. The primary bus for the PMCPCI adapter is that of the SBC, its secondary bus forming the P0 PCI backplane bus, which is also the primary bus for all of the attached P0CC1 cards. The secondary bus on each P0CC1 is connected to its PMC sites.

Manufactured in five air and conduction-cooled ruggedization levels, the P0CC1 offers fully compatible system expansion for the PPCx family of SBC's, providing both front and rear PMC I/O. The high density rear I/O is achieved using 5-row VME64 connectors, (the I/O actually being on P2). Full front and rear I/O is manufactured on air-cooled versions, with some limited front I/O also being manufactured for those conduction-cooled PMC's which have suitable connectors.
