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.
