ABSTRACT:
In a computer system processing out of order commands, a method for detecting situations in which errors could be caused by execution of an out of order command. The method includes the steps of receiving a first address of a first type and receiving a next address of the first type. Information is accumulated regarding differences between the first address and the next address. The method also includes receiving an address of a second type and using the accumulated information to determine whether the address of the second type is an address associated with a command whose execution can create a hazard. A hazard indication is generated if it is determined that the address of the second type is an address associated with a command whose execution can create a hazard. In one embodiment, the first type of address is an address associated with a first type of command and the second type of address is an address associated with a second type of command. In another embodiment, the first type of command and the second type of command are the same type of command.
