NettetThe LOCK # signal is asserted during execution of the instruction following the lockprefix. This signal can be used in a multiprocessor system to ensure exclusive use of shared memory while LOCK # is asserted. The btsinstruction is the read-modify-write sequence used to implement test-and-run. NettetThe LOCK prefix is typically used with the BTS instruction to perform a read-modify-write operation on a memory location in shared memory environment. The integrity of the LOCK prefix is not affected by the alignment of the memory field. Memory locking is observed for arbitrarily misaligned fields. Flags
