Processor Board
The 7030 processor board contains a microprocessor and support circuitry,
as shown in Figure 3-3. The support circuitry includes a chipset with PCI
controller and ISA bridge, main memory (DRAM), L2 cache (SRAM), and
BIOS. The LabVIEW RT software uses this embedded processor system
for its execution platform.
The DAQ daughterboard resides on the embedded PCI bus as shown in
Figure 3-3. This provides a high-performance system for communication
between the software running on the processor and the DAQ
daughterboard.
The processor board also holds the shared memory that communicates
between the host system and the embedded processor. Refer to the
Host-to-RT Series DAQ Board Communication section later in this chapter
and to Chapter 3, Software Overview, of the LabVIEW RT User Manual,
for more information about using shared memory for your applications.
