Hi,
in DSP BIOS 5.41.13.42, the Sem_Obj structure, defined in file sem.h
#ifdef PRIORITY
/*
* bit mask for SEM_Attrs 'type' field -- default is (0x0)
*/
#define SEM_FIFO 0x0
#define SEM_PRIORITY 0x1
#endif
typedef struct SEM_Obj {
KNL_Job job; /* handles interrupt-level posting */
Int count; /* semaphore value */
QUE_Obj pendQ; /* tasks wait here */
String name; /* printable name */
#ifdef PRIORITY
Uns type; /* bit mask SEM_PRIORITY (0x1) or SEM_FIFO (0x0) */
#endif
} SEM_Obj;
implies as if the semaphore processing can be configured with respect to priority.
It's assumed that it determines in which order pending tasks are executed -
either in the sequence in which they have registered (SEM_FIFO) or in dependence
of their task priority (SEM_PRIORITY).
Is this assumption correct? And if this is configurable, can you say how the type parameter can be
configured inside CCS?
Best regards
Jörg
