5.21.2 AXIS Support
AXIS is a set of software modules that can be used to accelerate the design,
development, testing, and deployment of complex digital signal processor (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 SBC347A, 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 SBC347A-xxxx1xxx). Also, these signals must not be
connected to any external loads that can interfere with their operation.
AXIS Timestamp Registers (0x648 to 0x64D)
