Data Structure Documentation

◆ dif_rv_core_ibex_addr_translation_mapping

struct dif_rv_core_ibex_addr_translation_mapping

Address translation matching region.

The value programmed is done at power-of-2 alignment. For example, if the intended matching region is 0x8000_0000 to 0x8000_FFFF, the value programmed is 0x8000_7FFF.

The value programmed can be determined from the translation granule. Assume the user wishes to translate a specific 64KB block to a different address: 64KB has a hex value of 0x10000. Subtract 1 from this value and then right shift by one to obtain 0x7FFF. This value is then logically OR'd with the upper address bits that would select which 64KB to translate.

Definition at line 56 of file dif_rv_core_ibex.h.

Data Fields
uintptr_t	matching_addr	Matching address (Virtual address). When an incoming transaction matches the matching region, it is redirected to the new address. If a transaction does not match, then it is directly passed through.
uintptr_t	remap_addr	Remap address (Physical address). The region where the matched transtaction will be redirected to.
size_t	size	Address region size.

◆ dif_rv_core_ibex_nmi_state

When the CPU encounters a double fault, the current crash dump is moved to previous, and the new crash dump is shown in current.

Definition at line 205 of file dif_rv_core_ibex.h.

Data Fields
dif_toggle_t	double_fault	`kDifToggleEnabled` if a double fault happened, otherwise `kDifToggleDisabled`
