The Idle Loop
4-54
RTA_dispatcher is a real-time analysis server on the target that accepts
commands from DSP/BIOS Analysis Tools, gathers instrumentation
information from the target, and uploads it at run time. RTA_dispatcher
sits at the end of two dedicated HST channels; its commands/responses
are routed from/to the host via LNK_dataPump.
IDL_cpuLoad uses an STS object (IDL_busyObj) to calculate the target
load. The contents of this object are uploaded to the DSP/BIOS Analysis
Tools through RTA_dispatcher to display the CPU load.
RTDX_dataPump calls RTDX_Poll on the C5400 platform to transfer
data between the target and the host. This occurs only if the DSP has
enough free cycles to execute the IDL loop on a regular basis. For the
C55x and C6000 platforms, RTDX is an interrupt driven interface (as
described for the LNK_dataPump object), and there is no
RTDX_dataPump object.
