VME64 to PMC bus-to-bus adapter with DMA

820

Overview


The VME64 to PMC bus-to-bus adapter directly connects two buses. The virtual bus created allows the two systems to operate as one enabling seamless operation, superior performance, the combined benefits of two diverse systems. The adapter allows each bus to operate independently. The timing of the two buses is linked only when a memory or I/O reference is made to one system that translates to a reference on the other. Therefore, bus bandwidth is not affected during non-transfer periods. Because the adapter does not require protocol stacks, it transfers data very efficiently. Remote data can be accessed directly by the processor as if it were stored in local hardware memory. Or, it can be transferred to local memory using the DMA engine. Either way, the adapter is designed to transfer data with minimum processor loading. A comprehensive suite of software drivers is provided for the PCI card to minimize integration time. In most cases, applications can be up and running in a few days. Drivers for Solaris, IRIX, Windows XP/2000, VxWorks and Linux are provided.
