• Random access memory (RAM). The Matrox 4Sight GPm motherboard has two
204-pin SO-DIMM slots, each slot supporting a SO-DIMM, unbuffered DDR3
SDRAM module. All Matrox 4Sight GPm units can have one or two identical
memory modules installed.
Note that SO-DIMM are factory installed and are not accessible to the user
❖
because of their location (in the thermal insulating material on the reverse-side
of the motherboard).
• Basic input/output system (BIOS). Flash memory is used to store the BIOS.
• I/O command lists. The Matrox 4Sight GPm motherboard has two I/O
command lists, each of which allow you to schedule commands to change the state
of a bit of an I/O command register at a specified time or counter value. The state
of the bits can be routed to auxiliary output signals or can be used, for example,
to trigger a timer.
• Integrated rotary decoders. The 2 integrated rotary decoders can decode
quadrature input received from a rotary encoder.
• Timers. The Matrox 4Sight GPm motherboard has 16 32-bit timers.
• Serial ports. The 2 serial ports (COM ports) are used to communicate with
RS-232 standard devices. Note that one of the two serial ports can also
communicate with RS-485 standard devices.
• Audio interfaces. One 24-bit stereo audio input connector, and one 24-bit audio
output connector.
• USB interfaces. USB interfaces are available to connect a USB keyboard, mouse,
and printer. Matrox 4Sight GPm (Ivy Bridge) has 6 USB interfaces (4 USB 3.0
and 2 USB 2.0), whereas Matrox 4Sight GPm (Bay Trail) has 3 USB interfaces
(1 USB 3.0 and 2 USB 2.0).
