Hardware cross-triggering
A hardware cross-triggering
mechanism uses the cross-trigger network (composed of Cross Trigger
Interface (CTI) and Cross Trigger Matrix (CTM) devices) present in a
multiprocessor system. The advantage of using a hardware-based
cross-triggering mechanism is low latency performance.
Software cross-triggering
In a software cross-triggering scenario, the
mechanism is performed and managed by the debugger. Using a software
cross-triggering mechanism results in increased latency.
In DS-5,
the Platform Configuration Editor (PCE) generates support for CTI-synchronized SMP
and
big.LITTLE™
debug operations platforms provided that sufficient and appropriate cores, and CTI
are available in the SoC. PCE also supports for transporting trace trigger
notifications across the cross-trigger network between trace sources and trace
sinks.
CTI interfaces need to be programmed using the Debug and Trace Services Layer (DTSL)
capabilities in
DS-5. See the
DTSL documentation or contact your support representative for more information.
