Abstract
Apparatuses and methods of operating such apparatuses are disclosed. Vector processing circuitry performs data processing in multiple parallel processing lanes, wherein the data processing is performed in a subset of the multiple parallel processing lanes determined by bit values of a vector predicate which are set. Predicate monitoring circuitry is responsive to the vector predicate to generate a predicate summary value in dependence on the bit values of the vector predicate. A first value of the predicate summary value indicates that a sparse condition is true for the vector predicate, the sparse condition being true when the bit values of the vector predicate comprise a set bit corresponding to a vector element at a higher index immediately followed by a non-set bit corresponding to a vector element at a lower index. A second value of the predicate summary value indicates that the sparse condition is not true for the vector predicate. Improved predicate controlled vector processing is thus supported.
