PMC
Our range of PCI
Mezzanine Card (PMC) building block products provide the flexibility to
easily expand I/O functionality and performance within an embedded computer
system.

PMC Module
Products
The PMC’s standard PCI
electrical interface, combined with a rugged mechanical mounting and
reliable electrical connectors, enable it to work reliably in more
applications than ordinary commercial-grade PCI modules. The extremely
popular single PMC (74 mm by 149 mm) is the perfect size for a wide range
of I/O functions, as well as for more complex interfaces such as ATM or
T1/E1 – as demonstrated by the rapidly increasing use of PMC communications
adapters within the telecom industry.

Processor
PMC
A decrease in the space occupied
by the processing core devices, resulting from the integration of the
central processing unit (CPU), memory controllers and bridges into a single
chip, provided the opportunity for the implementation of a new class of
processing module called a Processor PMC (PrPMC). The VITA 32 Processor PMC
standard specifies this new PrPMC macro component. It redefines 15 of the
PMC interface signals to support the PrPMC as a master and target CPU
rather than simply as an I/O device. A tall option is added to accommodate
heat sinks and support higher device power dissipation.

Two basic system
architectures are possible using Processor PMCs. One architecture uses the
PrPMC as a host CPU, which is connected to a baseboard full of PCI-based
I/O interfaces. A second architecture uses the Processor PMC as an
additional CPU.
