摘要:
The described embodiments include a processor that handles faults. The processor first receives an input vector, a control vector, and a predicate vector, each vector comprising a plurality of elements. Then, for a first element of the input vector for which corresponding elements of the control vector and the predicate vector are active, the processor performs a scalar read operation using an address from the element of the input vector. When a fault condition is encountered while performing the read operation, the processor determines if the element is a first element where a corresponding element of the control vector is active. If so (i.e., if the element is a first element where a corresponding element of the control vector is active), the processor processes the fault. Otherwise, the processor masks the fault for the element.
