Abstract
An apparatus and method are provided for maintaining lock characteristics while providing selective access to a cache during lock cycles. To guarantee that only one master accesses memory at a time, locked cycles are always passed to the internal arbitration unit of the memory controller, even if they are cache hits. If the local bus is not granted or cannot be guaranteed that it will be granted the bus for the locked cycle, the cycle is cancelled.
