Detailed Description

Functions that configure Instruction and Data cache.

Macro Definition Documentation

◆ __SCB_DCACHE_LINE_SIZE

#define __SCB_DCACHE_LINE_SIZE   32U

Cortex-M7 cache line size is fixed to 32 bytes (8 words). See also register SCB_CCSIDR

◆ __SCB_ICACHE_LINE_SIZE

#define __SCB_ICACHE_LINE_SIZE   32U

Cortex-M7 cache line size is fixed to 32 bytes (8 words). See also register SCB_CCSIDR

Function Documentation

◆ SCB_CleanDCache()

__STATIC_FORCEINLINE void SCB_CleanDCache ( void  )

Clean D-Cache.

Cleans D-Cache

◆ SCB_CleanDCache_by_Addr()

__STATIC_FORCEINLINE void SCB_CleanDCache_by_Addr ( volatile void *  addr,
int32_t  dsize 
)

D-Cache Clean by address.

Cleans D-Cache for the given address D-Cache is cleaned starting from a 32 byte aligned address in 32 byte granularity. D-Cache memory blocks which are part of given address + given size are cleaned.

Parameters
[in]addraddress
[in]dsizesize of memory block (in number of bytes)

◆ SCB_CleanInvalidateDCache()

__STATIC_FORCEINLINE void SCB_CleanInvalidateDCache ( void  )

Clean & Invalidate D-Cache.

Cleans and Invalidates D-Cache

◆ SCB_CleanInvalidateDCache_by_Addr()

__STATIC_FORCEINLINE void SCB_CleanInvalidateDCache_by_Addr ( volatile void *  addr,
int32_t  dsize 
)

D-Cache Clean and Invalidate by address.

Cleans and invalidates D_Cache for the given address D-Cache is cleaned and invalidated starting from a 32 byte aligned address in 32 byte granularity. D-Cache memory blocks which are part of given address + given size are cleaned and invalidated.

Parameters
[in]addraddress (aligned to 32-byte boundary)
[in]dsizesize of memory block (in number of bytes)

◆ SCB_DisableDCache()

__STATIC_FORCEINLINE void SCB_DisableDCache ( void  )

Disable D-Cache.

Turns off D-Cache

◆ SCB_DisableICache()

__STATIC_FORCEINLINE void SCB_DisableICache ( void  )

Disable I-Cache.

Turns off I-Cache

◆ SCB_EnableDCache()

__STATIC_FORCEINLINE void SCB_EnableDCache ( void  )

Enable D-Cache.

Turns on D-Cache

◆ SCB_EnableICache()

__STATIC_FORCEINLINE void SCB_EnableICache ( void  )

Enable I-Cache.

Turns on I-Cache

◆ SCB_InvalidateDCache()

__STATIC_FORCEINLINE void SCB_InvalidateDCache ( void  )

Invalidate D-Cache.

Invalidates D-Cache

◆ SCB_InvalidateDCache_by_Addr()

__STATIC_FORCEINLINE void SCB_InvalidateDCache_by_Addr ( volatile void *  addr,
int32_t  dsize 
)

D-Cache Invalidate by address.

Invalidates D-Cache for the given address. D-Cache is invalidated starting from a 32 byte aligned address in 32 byte granularity. D-Cache memory blocks which are part of given address + given size are invalidated.

Parameters
[in]addraddress
[in]dsizesize of memory block (in number of bytes)

◆ SCB_InvalidateICache()

__STATIC_FORCEINLINE void SCB_InvalidateICache ( void  )

Invalidate I-Cache.

Invalidates I-Cache

◆ SCB_InvalidateICache_by_Addr()

__STATIC_FORCEINLINE void SCB_InvalidateICache_by_Addr ( volatile void *  addr,
int32_t  isize 
)

I-Cache Invalidate by address.

Invalidates I-Cache for the given address. I-Cache is invalidated starting from a 32 byte aligned address in 32 byte granularity. I-Cache memory blocks which are part of given address + given size are invalidated.

Parameters
[in]addraddress
[in]isizesize of memory block (in number of bytes)
