- Processor ID option
- Selected
Processor ID enables external logic to set a unique identifier for each processor in a
system. This option is useful when a single piece of code executing on multiple
processors wants to know which processor is invoking the instruction. The value of the
id can be accessible in C as
follows:
#include <xtensa/tie/xt_core.h>
int my_id = XT_RSR_PRID();
