/** \defgroup pmu8_functions PMU Functions for Armv8.1-M \brief Functions that relate to the Performance Monitoring Unit. \details The following functions support the Performance Monitoring Unit (PMU) that is available on the Cortex-M55/M85 processors. The PMU is used to monitor events that occur during run-time of an application. Example: \code // Initialize counter variables unsigned int cycle_count = 0; unsigned int l1_dcache_miss_count = 0; unsigned int instructions_retired_count = 0; // Enable the PMU // Note: Before using the PMU, software needs to ensure // that trace is enabled via the Debug Exception Monitor Control Register, DEMCR: // CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk; ARM_PMU_Enable(); // Configure Event Counter Register 0 to count instructions retired // Configure Event Counter Register 1 to count L1 D-Cache misses ARM_PMU_Set_EVTYPER(0, ARM_PMU_INST_RETIRED); ARM_PMU_Set_EVTYPER(1, ARM_PMU_L1D_CACHE_MISS_RD); // Reset Event Counters and Cycle Counter ARM_PMU_EVCNTR_ALL_Reset(); ARM_PMU_CYCCNT_Reset(); // Start incrementing Cycle Count Register and Event Counter Registers 0 & 1 ARM_PMU_CNTR_Enable(PMU_CNTENSET_CCNTR_ENABLE_Msk|PMU_CNTENSET_CNT0_ENABLE_Msk|PMU_CNTENSET_CNT1_ENABLE_Msk); // Code you want to measure here // Stop incrementing Cycle Count Register and Event Counter Registers 0 & 1 ARM_PMU_CNTR_Disable(PMU_CNTENCLR_CCNTR_ENABLE_Msk|PMU_CNTENCLR_CNT0_ENABLE_Msk|PMU_CNTENCLR_CNT1_ENABLE_Msk); // Get cycle count, number of instructions retired and number of L1 D-Cache misses (on read) cycle_count = cycle_count + ARM_PMU_Get_CCNTR(); instructions_retired_count = instructions_retired_count + ARM_PMU_Get_EVCNTR(0); l1_dcache_miss_count = l1_dcache_miss_count + ARM_PMU_Get_EVCNTR(1); // Note: D-Cache must be enabled using // SCB_EnableDCache() for meaningful result. \endcode @{ */ /** \defgroup pmu8_events_armv81 PMU Events for Armv8.1-M \ingroup pmu8_functions \brief IDs for Armv8.1-M architecture defined events. \details These events are available on all Armv8.1-M devices including a PMU. @{ */ #define ARM_PMU_SW_INCR 0x0000 /*!< \brief Software update to the PMU_SWINC register, architecturally executed and condition code check pass */ #define ARM_PMU_L1I_CACHE_REFILL 0x0001 /*!< \brief L1 I-Cache refill */ #define ARM_PMU_L1D_CACHE_REFILL 0x0003 /*!< \brief L1 D-Cache refill */ #define ARM_PMU_L1D_CACHE 0x0004 /*!< \brief L1 D-Cache access */ #define ARM_PMU_LD_RETIRED 0x0006 /*!< \brief Memory-reading instruction architecturally executed and condition code check pass */ #define ARM_PMU_ST_RETIRED 0x0007 /*!< \brief Memory-writing instruction architecturally executed and condition code check pass */ #define ARM_PMU_INST_RETIRED 0x0008 /*!< \brief Instruction architecturally executed */ #define ARM_PMU_EXC_TAKEN 0x0009 /*!< \brief Exception entry */ #define ARM_PMU_EXC_RETURN 0x000A /*!< \brief Exception return instruction architecturally executed and the condition code check pass */ #define ARM_PMU_PC_WRITE_RETIRED 0x000C /*!< \brief Software change to the Program Counter (PC).
