Abstract:
In an embodiment, a processor may include a completion time determination circuit. The completion time determination circuit may be configured to receive one or more source operands of a vector memory operation used to produce the addresses of the vector elements accessed by the vector memory operation. The completion time determination circuit may be configured to determine a completion time for the vector memory operation (e.g. based on a number of TLB accesses, a number of cache accesses, and/or other aspects of the vector memory operation). The completion time determination circuit may provide the completion time to an issue circuit, which may use the completion time to schedule operations dependent on the vector memory operation, if any.
