Detailed Description
Function Documentation
| IFX_INLINE uint32 IfxCpu_getClockCounter | ( | void | ) |
| IFX_INLINE boolean IfxCpu_getClockCounterStickyOverflow | ( | void | ) |
API to get sticky overflow bit of clock counter for the CPU, which calls this API.
This API can be used to get sticky overflow bit of clock counter of only the caller CPU. It cannot be used for this activity towards other CPUs. This API also clears the sticky overflow after the read. While reading the sticky bit this API disables the counter for short time. (otherwise sticky bit cannot be cleared). This API shall be used after reading the counter
- Returns
- Status of sticky overflow bit.
- Return values
-
TRUE,: Sticky overflow bit is set. FALSE,: Sticky overflow bit is reset
| IFX_INLINE uint32 IfxCpu_getInstructionCounter | ( | void | ) |
| IFX_INLINE boolean IfxCpu_getInstructionCounterStickyOverflow | ( | void | ) |
API to get sticky overflow bit of Instruction counter for the CPU, which calls this API.
This API can be used to get sticky overflow bit of Instruction counter of only the caller CPU. It cannot be used for this activity towards other CPUs. This API also clears the sticky overflow after the read. While reading the sticky bit this API disables the counter for short time. (otherwise sticky bit cannot be cleared). This API shall be used after reading the counter
- Returns
- Status of sticky overflow bit.
- Return values
-
TRUE,: Sticky overflow bit is set. FALSE,: Sticky overflow bit is reset
| IFX_INLINE uint32 IfxCpu_getPerformanceCounter | ( | uint32 | address) |

| IFX_INLINE void IfxCpu_resetAndStartCounters | ( | IfxCpu_CounterMode | mode) |
| IFX_INLINE void IfxCpu_setPerformanceCountersEnableBit | ( | uint32 | enable) |
API to enable or disable performance counter for the CPU which calls this API.
This API can be used to enable or disable performance counter of only the caller CPU. It cannot be used for this activity towards other CPUs.
- Parameters
-
enable enable Command to enable or disable the performance counter. TRUE: Enable the performance counter. FALSE: Disable the performance counter
- Returns
- None
| IFX_INLINE IfxCpu_Perf IfxCpu_stopCounters | ( | void | ) |
Stop instruction and clock counters, return their values.
Stop CCNT, ICNT, M1CNT, M2CNT, M3CNT and return their values; The CCTRL is reset to 0, for more accurate measurements and has to be initialized again before strating the next performance measurement.
- Returns
- Performance counter result
| IFX_INLINE void IfxCpu_updateClockCounter | ( | uint32 | count) |
API to update clock counter for the CPU which calls this API.
This API can be used to update clock counter of only the caller CPU. It cannot be used for this activity towards other CPUs.
- Parameters
-
count Counter value to be updated. 0 to 0x7FFFFFFF
- Returns
- None
| IFX_INLINE void IfxCpu_updateInstructionCounter | ( | uint32 | count) |
API to update Instruction counter for the CPU which calls this API.
This API can be used to update Instruction counter of only the caller CPU. It cannot be used for this activity towards other CPUs.
- Parameters
-
count Counter value to be updated. 0 to 0x7FFFFFFF
- Returns
- None
| IFX_INLINE void IfxCpu_updatePerformanceCounter | ( | uint32 | address, |
| uint32 | count | ||
| ) |
