This unit
The Abaco Systems / SBS / Bit 3 85221511 is a PCI adapter module that bridges PCI and VMEbus architectures through an integrated DMA controller. This card enables bi-directional bus mastering from either system, permitting the PCI subsystem to function as a coprocessor or bus master on VMEbus, or allowing VMEbus devices to access PCI memory directly. The module sustains data transfer rates up to 26 MB/s from PCI system memory to VMEbus and exceeds 10 MB/s for VMEbus DMA devices writing into PCI memory.
It supports both 16-bit and 32-bit data transfers with parity protection across address, control, and data lines to maintain interface integrity.
