The Idle Loop
4-50
❏ 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.
❏ PWRM_idleDomains calls a function to idle various DSP clock domains
within the DSP/BIOS idle loop. Various clock domains to idle can be
selected in the PWRM module configuration. When a HWI, SWI, or TSK
thread is ready to run, the idled clock domains are restored to their
previous configuration.
