BYTE SWAPPING — The Intel 80x86 family ofprocessors uses little-endian format. To accommodate
VMEbus modules that transfer data in big-endian format,
such as the 680x0 processor family, the VMIVME-7700
incorporates byte-swapping hardware. This provides
independent byte swapping for both the master and slave
interfaces. Both master and slave interface byte swapping are
under software control. The VMIVME-7700 supports high
throughput DMA transfers of bytes, words and longwords in
both Master and Slave configurations. If endian conversion
is not needed, we offer a special “bypass” mode that can be
used to further enhance throughput. (Not available for byte
transfers.)
MASTER INTERFACE — MA32: MBLT32:
MBLT64 (A32:A24:A16:D32:D16:D8 (EO):BLT32)
The VMEbus master interface provides nine separate
memory windows into VMEbus resources. Each window
has separate configuration registers for mapping PCI bus
transfers to the VMEbus (that is, PCI bus base address,
window size, VMEbus base address, VMEbus access type,
VMEbus address/data size, etc.). The maximum/minimum
window sizes for the nine windows are as follows:
Window Minimum Size Maximum Size
0,4 4 KB 4 GB
1 to 3, 5 to 7 64 KB 4 GB
Special Cycle 64 MB 64 MB
SLAVE INTERFACE — Memory Access
SAD032:SD32:SBLT32:SBLT64 (A32:A24:A16:D32:D16:
D8 (EO): BLT32)
The VMEbus slave interface provides eight separate
memory windows into PCI resources. Each window has
separate configuration registers for mapping VMEbus
transfers to the PCI bus (that is, VMEbus base address,
window size, PCI base address, VMEbus access type,
VMEbus address/data size, etc.). The maximum/minimum
window sizes for the eight windows are as follows:
Window Minimum Size Maximum Size
0,4 4 KB 4 GB
1 to 3, 5 to 7 64 KB 4 GB
In addition, each window can be programmed to
operate in coupled or decoupled mode. In decoupled mode,
the window utilizes a write-posting FIFO and/or a read
prefetching FIFO for increased system performance. In
coupled mode, the FIFOs are bypassed and VMEbus
transactions are directly coupled to the PCI bus (that is,
transfers on VMEbus are not completed until they are
completed on the PCI bus).
ENHANCED BUS ERROR HANDLING —
Enhancements over the Universe chip’s bus error handling
features are provided. A latch and register are provided to
allow the SBC to read the VMEbus address that caused the
bus error in all modes. The Universe chip’s support is limited
to decoupled mode. Support for bus cycle timeout and
assertion of bus error is provided. The board may be
configured to assert bus error upon timeout regardless of its
status as system controller. The Universe chip asserts bus
error only if it is the system controller. In addition, this board
may be configured to assert an interrupt upon bus cycletimeout.

BACK PANEL CONFIGURATION — The
VMIVME-7700 provides support for external IDE disk drive
and floppy drive through the VMEbus P2 backplane
connector and the VMIACC-0562 backplane adapter.
OPERATING SYSTEM AND SOFTWARE
SUPPORT — The VMIVME-7700 provides embedded
features beyond PC/AT functionality. These features are
supported by VMIC software products aimed at developers
who are incorporating VMIC SBCs, I/O boards and
workstations into systems. The VMIVME-7700 supports a
variety of operating systems including Microsoft® Windows
NT®, Windows® 2000, Windows XP, QNX, Linux® and
VxWorks®.
