摘要： The present invention provides for executing load instructions with a processor having a non-blocking cache memory, wherein individual load operations are dispatched to the cache memory and the cache memory signals the prevent the load operation from being sent to external memory when the load operation misses the cache memory and there is already a currently pending bus cycle to the same cache line. This helps reduce bus traffic on the external bus.

摘要： A method and apparatus for dispatching load operations in a computer system. The present invention includes a method and apparatus for determining when the load operation is ready for dispatched to memory. The load operation is then scheduled to dispatch from memory and then dispatched to memory. In the present invention, a load is determined ready when it is no longer blocked, such that there is no condition which produces a resource or address dependency causing the load to be blocked.

摘要： The present invention provides for executing store instructions with a processor. The present invention executes each of the store instructions by producing the data that is to be stored and by calculating the destination address to which the data is to be stored. In the present invention, the store instructions are executed to produce the destination address of the store instruction earlier than the prior art.

摘要： A method and apparatus for performing load operations in a computer system. The present invention includes a method and apparatus for dispatching the load operation to be executed. The present invention halts the execution of the load operation when a dependency exists between the load operation and another memory operation currently pending in the system. When the dependency no longer exists, the present invention redispatches the load operation so that it completes.
