Bus. If this happens, the arbitration unit gives the CompactPCI Bridge device priority
and services the HOST CompactPCI access before giving bus ownership back to the
DSP.
When running code composer applications to debug the DSP a reduction in the
speed of the debugger may be noticed. The DSP has priority when accessing the
local bus and any other accesses will only occur under the following conditions.
• Burst access finishes
• A deadlock condition occurs which forces the DSP to release ownership of the
Bus.
For multi-threaded applications the length of the DSP burst can be lowered to allow
CompactPCI bus R/W cycles to snatch cycles from the DSP.
