Compatible with Windows NT* and based on the Intel Pentium processor, the EPC-9 is the first VME product that can be field-upgraded. The EPC-9 exemplifies high integration, reliability and performance. Its flexible design allows for customization to fit specific applications. It uses the Peripheral Component Interconnect (PCI) local bus for maximum performance and integration. Through advanced silicon technology, RadiSys incorporates the PCI local bus as a low latency interface between the microprocessor/memory subsystem and peripheral components. For applications requiring video, RadiSys also provides an optional PCI-based SVGA PMC module based on the Cirrus Logic CL GD5446. The EPC-9 uses the 16-bit PC/AT-like EXM expansion bus in addition to the 32-bit PCIbus and 32-bit VMEbus. The EXM expansion bus design facilitates local embedded PC expansion without interfering with the host VMEbus, maximizing system performance. I/O, mass storage, 8-bit PC add-in short cards, and other expansion modules can be added easily. Since EXM modules are electrically similar to the PC/AT bus, they can be customized to accommodate the EPC-9 mechanical configuration.
