Figure 2-1. VXIpc 700 Series Block Diagram

The VXIpc-700 consists of the following logic blocks:
• IDE—This is dedicated PCI-IDE circuitry providing fast ATA-2
transfers to the internal hard drive. The IDE for the VXIpc 700 Series
is built into the chip set.
• VXI—This is the PCI-VXIbus interface circuitry. The MITE is a
National Instruments ASIC developed to efficiently manage data
transfers between the VXIbus and the processor (via the PCI bus). The
MANTIS ASIC (also developed by National Instruments) performs
VXIbus arbitration and manages interrupts and triggers. Also part of
the VXIbus interface are the SMB connectors, which you can use to
route triggers and the CLK10 signal to or from the VXIbus.
