Description

The GE Fanuc / SBS / Bit 3 487-1 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.
