Functions

void memoryProtection_init(AddressType codeMemoryHighAddress, AddressType codeMemoryLowAddress, AddressType stackMemoryHighAddress, AddressType stackMemoryLowAddress, AddressType unprotectedMemoryLowAddress, AddressType unprotectedMemoryHighAddress)

Memory protection initialization. DEMO.

The implementation contains CILmemoryProtection_init function call.

Parameters

• codeMemoryHighAddress – [in]

• codeMemoryLowAddress – [in]

• stackMemoryHighAddress – [in]

• unprotectedMemoryLowAddress – [in]

• unprotectedMemoryHighAddress –

Returns

none

void memoryProtection_setMemoryProtection(CosmOS_CoreConfigurationType *core, CosmOS_SchedulableConfigurationType *schedulable)

Set memory protection for current execution context that means for the schedulable stack, peripheral access and program memory. This function cannot be called from the unprivileged context directly.

The implementation contains obtaining of the program id and program variable by calling schedulable_getProgramId and core_getCoreProgramCfg functions. From the schedulable variable argument is also extracted its stack configuration by calling schedulable_getStack. After this point the memory protection is set for the stack, peripheral and program memory by calling functions memoryProtection_setStackOverflowProtection, memoryProtection_setProgramMemoryProtection and memoryProtection_setSchedulablePeripheralProtection.

Parameters

• core – [in] configuration pointer

• schedulable – [in] configuration pointer

Returns

none

CosmOS_BooleanType memoryProtection_isMemoryRegionProtected(CosmOS_CoreConfigurationType *core, AddressType *regionLowAddressPointer, BitWidthType size)
