VXIpc 800/700 Series User Manual
ASIC to perform the fastest transfer operation to instruments. With the
multiple windowing scheme of the MITE, you can easily access all of
VXI address space.
The VXI trigger interface on the VXIpc 800/700 is based on the
MANTIS custom ASIC. The VXIpc 800/700 front panel has two SMB
trigger I/O connectors, which you can use to route any of the TTL
trigger lines between the backplane and external devices. The MANTIS
ASIC on the VXIpc 800/700 provides the complete VXI interface to the
backplane connector in a single chip. The VXIpc 800/700 can respond
to all VXI-defined protocols on all P2 TTL and ECL trigger lines at the
same time. The MANTIS features an internal cross-matrix switching
system for routing between lines as well as to and from the front panel
and onboard clocks.
Note:
The MANTIS ASIC contains the exact functionality of the TIC ASIC,
which appeared on the VXIpc-486 Model 500 Series controllers. Any
application that currently uses any of the TIC functionality, such as the
crosspoint switch and counter/timers, can run on a controller containing
the MANTIS ASIC without modification.
