    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.

    摘要: Instructions and logic provide SIMD address conflict detection functionality. Some embodiments include processors with a register with a variable plurality of data fields, each of the data fields to store an offset for a data element in a memory. A destination register has corresponding data fields, each of these data fields to store a variable second plurality of bits to store a conflict mask having a mask bit for each offset. Responsive to decoding a vector conflict instruction, execution units compare the offset in each data field with every less significant data field to determine if they hold a matching offset, and in corresponding conflict masks in the destination register, set any mask bits corresponding to a less significant data field with a matching offset. Vector address conflict detection can be used with variable sized elements and to generate conflict masks to resolve dependencies in gather-modify-scatter SIMD operations.
