5.22.2 AXIS Support
AXIS (Advanced Multiprocessor Integrated Software) is a set of software modules
that can be used to accelerate the design, development, testing and deployment of
complex DSP and multiprocessing platforms for real-time applications such as radar,
sonar, communications and image processing.
AXIS requires two external hardware signals (AXIS_CLK and AXIS_RST) to allow
boards to synchronize over the backplane while running AXIS software.
On the SBC329, these signals are shared with GPIO(2) and GPIO(3) respectively. For
AXIS to be fully supported, these signals must be available (i.e. the build variant
must be SBC329-xxxx1xxxx or SBC329-xxxx3xxxx). Also, these signals must not be
connected to any external loads that can interfere with their operation.
See section 6.10 for information on the AXIS timestamp registers.
