Functions

void HAL_CACHE_Enable(uint32_t imode, uint32_t dmode)

Enable cache profiling.

参数:

  • imode – [in] ICache profiling mode bitmap, see icache profiling mode, could select multiple modes, such as HAL_CACHE_ICACHE_QSPI1_4|HAL_CACHE_ICACHE_QSPI2 for SF32LB55X

  • dmode – [in] DCache profiling mode bitmap, see dcache profiling mode, could select multiple modes, such as HAL_CACHE_DCACHE_QSPI1_4|HAL_CACHE_DCACHE_QSPI2 for SF32LB55X

返回值:

void –

void HAL_CACHE_Disable(void)

Disable cache profiling.

返回值:

void –

void HAL_CACHE_GetMissRate(float *irate, float *drate, bool reset)

Get ICACHE and DCACHE miss rate.

参数:

  • irate – [out] pointer of output icache miss rate, unit: percentage

  • drate – [out] pointer of output dcache miss rate, unit: percentage

  • reset – [in] true: reset all counters, false: do not reset counters

返回值:

void –
