Abstract: A microprocessor includes an N-way cache and a logic block that selectively enables and disables the N-way cache for at least one clock cycle if a first register load instructions and a second register load instruction, following the first register load instruction, are detected as pointing to the same index line in which the requested data is stored. The logic block further provides a disabling signal to the N-way cache for at least one clock cycle if the first and second instructions are detected as pointing to the same cache way.

Abstract: Disclosed are methods, systems, and computer program products for evaluating performance aspects of electrical circuits, and particularly digital logic circuits. An exemplary method comprises obtaining access to a simulation dump file comprising state indications of the values of a plurality of signals of an electrical circuit at a plurality of simulation time points, and receiving an evaluation task that defines an output based on one or more input signals, with each input signal being a signal for which state indications are provided in the simulation dump file. The method further comprises generating, from the simulation dump file, one or more state representations for the input signals of the evaluation task, with each state representation being representative of the state of an input signal over a period of simulation time, and generating values of the output of the evaluation task at a plurality of simulation time points from the state representations.
