CACHEI.WI
Cache Index, Writeback, Invalidate
Description
If the cache line at the memory index/way specified by the address register A[b] is present in the L1 data cache,
write back the modified data and then invalidate the line in the L1 data cache.
The address specified by the address register A[b] undergoes standard protection checks. Address register
updates associated with the addressing mode are performed regardless of the cache operation.
The location of way/index within A[b] is implementation dependent.
CACHEI.WIA[b], off10 (BO)(Base + Short Offset Addressing Mode)
index_way = A[b] + sign_ext(off10);
cache_index_wi(index_way);
CACHEI.WIA[b], off10 (BO)(Post-increment Addressing Mode)
index_way = A[b];
cache_index_wi(index_way);
A[b] = index_way + sign_ext(off10);
CACHEI.WIA[b], off10 (BO)(Pre-increment Addressing Mode)
index_way = A[b] + sign_ext(off10);
cache_index_wi(index_way);
A[b] = index_way;
