摘要:
A processor includes an execution unit, a fault mask coupled to the execution unit, and a suppress mask coupled to the execution unit. The fault mask is to store a first plurality of bit values to indicate which elements of a multi-element vector have an associated fault generated in response to execution of an instruction on the element in the execution unit. The suppress mask is to store a second plurality of bit values to indicate which of the elements are to have an associated fault suppressed. The processor also includes counter logic to increment a counter in response to an indication of a first fault associated with the first element and received from the fault mask, and an indication of a first suppression associated with the first element and received from the suppress mask. Other embodiments are described as claimed.
