The PCI-MXI-2 is a half-size, PCI-compatible plug-in circuit board that plugs into one of the expansion
slots in your PCI-based computer. It links your PCI-based computer directly to the MXIbus and vice versa.
Because the PCI-MXI-2 uses the same communication register set that other VXIbus message-based
devices use, other MXIbus devices view the PCI-MXI-2 as a VXIbus device. The PCI-MXI-2 can also
function as the MXIbus System Controller and can terminate the MXIbus signals directly on the PCI-MXI-2.
In addition, you can have up to 16 MB of onboard DRAM on the PCI-MXI-2 that can either be shared
with the MXIbus and VXI/VMEbus, or used as a dedicated data buffer.
The PCI-MXI-2 achieves high performance block transfer rates by integrating the MITE custom ASIC,
a sophisticated dual-channel DMA controller with standard interfaces for VXI, VME, MXI, and PCI. By
using MITE DMA to transfer data and commands to and from devices, the MITE frees up a computer’s
microprocessor to perform other tasks such as data analysis and presentation. In addition to DMA, the
MITE incorporates both the new Synchronous MXI protocol and VME64 MBLT (8-byte block transfers
in which both the address bus and data bus are used to transfer data) directly into the ASIC to perform
the fastest transfer operation to instruments.
The PCI-MXI-2 has the following features:
• Interfaces the PCI bus to the MXIbus (32-bit Multisystem eXtension Interface bus)
• Supports D64, block, and synchronous MXI cycles for high-performance data transfer
• Directly controls MXIbus interrupt levels, utility signals, TTL triggers, and CLK10
• Allows for optional or user-installable onboard DRAM up to 16 MB, which can be shared with the MXIbus
• Conforms to PCI specification 2.0
• Conforms to the MXIbus specification 2.0
• Supports MXI bus termination
