Abstract: A method and apparatus to generate test sequences for pipeline hazards in a pipelined data processing system is presented. An executable specification for the architecture is compiled that includes macroarchitecture and microarchitecture information corresponding to each of the instructions supported by the architecture. A table (20) is constructed from the executable specification that specifies the particular resource utilization parameters associated with each of the instruction types included in the instruction set supported. From this table a resource utilization parameter list (30) is compiled that indicates the relative times at which resources are needed by each instruction and when these resources are released by the instruction. Comparisons between different entries in the resource utilization parameter list corresponding to the same resource are performed such that potential hazards are detected.

Abstract: An electric power cable is provided having concentric neutral wires (CN wires) applied helically over the cable core construction to serve as a metallic ground shield and having a protective polymeric jacket over the CN wires. The cable is characterized in that at least one continuous, elongated water swellable element, such as yarn, filament, strand or strip is provided in contact with the CN wires and is so disposed in relation thereto as to block the passage of water within the cable in the longitudinal direction.
