Abstract
In an embodiment, a processor may implement a vector hazard check instruction to detect dependencies between vector memory operations based on the addresses of the vectors accessed by the vector memory operations. The addresses may be specified via a base address and a vector of indexes for each vector. In an embodiment, one of the base addresses may be an implied (or assumed) zero address, reducing the number of operands of the hazard check instruction.
