VXI/VME-PCI8022 Kit Overview

The VXI/VME-PCI8022 interface kits link any computer with a
PCI bus (hereafter referred to as a PCI-based computer) directly to the
VXIbus or VMEbus using the high-speed Mu ltisystem eXtension
Interface bus ( MXI -2).

A PCI-based computer e quipped wi th a VXI- PCI8 022 interf ace can
function as a VXI Commander and Resource Manager. A PCI-based
computer equipped w ith a VM E -PCI802 2 c a n fun ction a s a VM Eb us
master and/or slave devi ce. The V XI/VME -PCI802 2 makes your
PCI-based computer behave as though it were plugged directly into the
VXI/VME backplane as an embedded CPU VXI/VME module.

The software included with the kits is for Sparc-based computers.

What You Need to Get Started

❑ A PCI-based computer
❑ VXIbus or VMEbus mainframe

Chapter 1 Introduction and Quick Start

❑ PCI-MXI-2 interface board
❑ VXI-MXI-2 or VME-MXI-2 interface module
❑ MXI-2 cable
❑ NI-VXI software media for the PCI-MXI-2

MXI-2 Description

MXI-2 is the second g eneration of the Na tional I nstrume nts MX Ibu s
product line. The M XIbus is a gen eral- pur pose, 32-bit, mu ltimaster
system bus on a cab le. M XI-2 e xpand s the num be r of signa ls on a
standard MXI cable by including VX I triggers, all VX I interrupts,
CLK10, and all of the utility bus signals (SYSFAIL*, SYSRESET*,
and ACFAIL*).

Because MXI- 2 in co rpo ra tes al l o f th ese new signa ls in to a s in gl e
connector, the triggers, interrupts, and utility signals can be extended
not only to other mainframes but also to the local CPU in all MXI-2

Chapter 1 Introduction and Quick Start

products using a single cable. Thus, MXI-2 lets CPU interfac e boards
such as the PCI-MXI-2 perform as thou gh they were plugged direc tly
into the VXI/VME backplane.

In addition, MXI-2 boosts data thro ughp ut p erforma nce past p revious ­generation MXIbus produc ts b y d efini ng ne w high -perf orma nc e
protocols. MXI-2 is a superset of MXI. All accesses initiated by MXI
devices will work with MXI-2 devices. However, MXI-2 defines
synchronous MXI block data transfers which surpass previo us block
data throughput benchmarks. The new synchronous MXI block protocol
increases MXI-2 throu ghput to a maxim um of 3 3 MB/s between tw o
MXI-2 devices. All N ational Instruments MXI-2 boards are capable of
initiating and responding to synchronous MXI block cyc les.

Note: In the remainder of this manual, the term MXIbus refers to MXI-2.

Hardware Description

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 co mp uter d irectly to the M XIb us a nd v ice ver sa.
Because the PCI-MXI-2 uses the same communication register set that
other VXIbus message-based de vices use, othe r MXIbus de vices view
the PCI-MXI-2 as a VXIbus devic e. The PCI- MXI -2 can also func tion
as the MXIbus System Contro ller and can term inate the MXIbus signa ls
directly on the PCI-MXI- 2. In addition , you can have up to 16 M B of
onboard DRAM on the PCI-MXI-2 that can be shared with the MXIbus
and VXI/VMEbus and used as a dedicated data buffer.

The VXI-MXI-2 m odu le is a n exte nded- class, re gister- based V XIbu s
device with optional VXIbus Slot 0 capability so that it can reside in any
slot in a C-size or D-size chassis.

Note: D-size VXI mainframes have connections for a P3 connector. The

VXI-MXI-2, however, does not have this connector and, if configured as a
Slot 0 controller, cannot p rovide the ne cessary control for VXI device s that
need P3 support.

The VXI-MXI-2 uses ad dress ma pping to convert MXIbus cycl es into
VXIbus cycles and vice versa. By connecting to the PCI-MXI-2 board,
the VXI-MXI-2 links the PCI bus to the VXIbus. The VXI-MXI-2 can
automatically determine whether it is located in VXI Slot 0 and/or if it
is the MXIbus System Controller.

Chapter 1 Introduction and Quick Start

The VME-MXI-2 m odu le is a single- slot, doub le- heig ht VM Ebus
device with optional VMEbus System Controller functions. It uses
address mapping to convert MXIbus c ycles into VM Ebus cycle s and
vice versa, just like the VXI-MXI-2. By connecting to the PCI-MXI-2
board, it links the PCI bus to the VMEbus. The VME-MXI-2 can
automatically determine if it is located in the first slot of a VMEbus
chassis and if it is the MXIbus System Controller.

Also, the VXI-MXI-2 and VME-MXI-2 automatically terminate the
MXIbus if installed as the first or last device in the MX Ibus. If installed
in the middle of the MXIbus, both the VXI-M XI- 2 and VME- MXI-2
automatically disable MXIbus termination. In addition, you can have up
to 64 MB of onboard DRAM on the VXI -MXI-2 and VME-M XI-2
modules that can either be shared with the VXI/VMEbus and MXIbus
or used as a dedicated data buffer.

The PCI-MXI -2, V X I-MX I -2, a nd V M E-MX I- 2 produc t s a chi ev e
high-performance blo ck transfer rates by integra tin g the MITE custom
ASIC, a sophisticated dual-channel DMA controller with standard
interfaces for V XI, VM E, M XI, a nd P CI. B y u si ng MITE DM A t o
transfer data and command s 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 pr otocol an d V ME6 4 M BL T (8 -by t e bloc k
transfers in which both the address bus and data bus a re used to transfer
data) directly into the ASIC to perform the fastest transfer operation to
instruments.

Software Description
