【英文介绍】

 The main function of the VMIVME-HSD is to provide a high-performance 32-bit DMA link between the VMEbus and Encore HSD Interbus Link (IBL). It integrates the 68430 DMA controller chip to perform DMA transfers and provides the necessary logic to control transfers to and from the Encore HSD. In addition, the VMIVME-HSD contains logic that implements the VMEbus interrupter, as well as logic that allows the VMEbus to interrupt the Encore HSD.

Features:

32-bit DMA transfer

HSD compatibility

IBL compatibility

The VMIVME-HSD / -HSDA provides a high-performance 32-bit DMA link between the VMEbus and the Encore HSD Model 9132 and Encore Model 9136 Interbus links (IBL). The VMIVME-HSD / -HSDA integrates a 68430 DMA controller chip to perform its DMA transfers and provides the logic needed to control the VMEbus during transfers to and from the Encore HSD. The VMIVME-HSDA also contains logic for implementing the VMEbus interrupter and logic that allows the VMEbus to interrupt the Encore HSD.

Features:

• 32-bit DMA transfer

• HSD compatibility

• IBL compatibility

• Used as an HSD slave or HSD host (revised F-board)

• It can also be used as an IBL high-priority interface or an IBL low-priority interface

• Two board groups can serve as VME to VME links

• Compatible

VMEbus (IEEE P1014) • Programmable interrupt vectors and levels

• Programmable VMEbus address modifiers

• Fault indicator light

• Switch optional board address

• On-board register addressing using VME short I/O address space
