The GE Fanuc / SBS 487-1 EISA Bus to A32/D32 VMEbus with DMA is a fast, easy-to-use way to share memory and special purpose boards between an EISA-based computer and a VMEbus system. The Adapter provides high-speed data transfers between systems, and requires minimal software support. The Adapter gives you the best of both worlds by uniting the power of a VMEbus system with the EISA environment so that:
• Both systems can directly address resources at the remote end of the cable as though they were local.
• Blocks of data, I/O commands, and interrupts can be passed between systems.
Plus, the EISA-based system can function as either a co-processor or as the only bus master processor in a VMEbus chassis.
With the Bit 3 Adapter, each bus operates independently. The timing of the two buses is linked only when a memory or I/O reference is made to an address on one system that translates to a reference on the other. The integrity of the interface between Adapter cards is maintained by parity checks on address, control, and data lines. Model 487-1 supports A32/D32 random access cycles from either system and includes a built-in DMA controller. The DMA controller is a high-speed data mover engine that moves data between EISA system memory and the VMEbus at sustained data rates of up to 26M bytes per second (M Bytes/sec). It also allows a VMEbus DMA device (such as a disk controller) to DMA through the Adapter directly into EISA memory at data transfer rates in excess of 12M Bytes/sec. Actual performance rates are dependent on the capabilities of the specific EISA system and the speed of the VMEbus memory.
The SBS 85154550 VMEbus Adapter with DMA Controller Module may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
