VMEMM with PCIADA interface card

The PCI-VME system is a high-efficient VME-bus master VMEMM which can be operated by a PCI-bus based computer system via the PCIADA interface card. The direct access to the VME bus (A16/24/32, D8/16/32) is given.

Due to the differential data transfer between VME master VMEMM and PCI interface PCIADA (32-bit parallel with hardware handshake) maximum data transfer rates between the VME bus and the computer housing the PCIADA card can be reached.

VMEMM Controller

• single slot 6 U VME master (A16, A24, A32/D8, D16, D32) with system controller functions (SYSCLK, SYSRESET, Arbiter, IACKdriver, BGI-driver), can be configured
• VME interface based on Cypress VIC068A
• programmable arbiter (SGL, PRIO, RRS) and requester (ROR, RWD)
• programmable bus time-out function - byte, word and longword data transfer
• selectable interrupt handler and requester for all 7 VME interrupt levels
• RMC, VME-SYSFAIL and ACFAIL support
• Front panel with LED's for +5 V, system controller function, VME access, local access and VME interrupt and push button for SYRES
• interface connector: 50-pin SCSI2 type, max. 10 m
