Abstract: The disclosure relates to a method for detecting a standstill of a vehicle, said method comprising a step of filtering, a step of normalizing and a step of observing. In the filtering step, an acceleration value in a first axis of the vehicle and a rotational speed value about a second axis of the vehicle, oriented orthogonally to the axis, are filtered using a filter specification in order to obtain a filtered acceleration value and a filtered rotational speed value. In the normalizing step, the filtered acceleration value and the filtered rotational speed value are normalized using a normalization specification in order to obtain a normalized acceleration value and a normalized rotational speed value. In the observation step, the normalized acceleration value and the normalized rotational speed value are observed using an observation specification in order to detect the standstill.

Abstract: A method and apparatus automatically and easily verifies a cache line prefetch mechanism. The verification method includes a strict definition of which cache lines should be prefetched and which cache lines should not. The method also emphasizes unusual operating conditions. For example, by exercising boundary conditions, the method by stresses situations in which a microprocessor or chip is likely to produce errors. The method can verify prefetch without having to access or view any internal signals or buses inside the chip. The method can be adopted in any system-level verification methodology in simulation, emulation, or actual hardware. The method can be used in a system-level test set up along with a chip-level test set up without requiring knowledge of the internal state of the chip. In this case, checking is done at the chip boundary. The method is automated and performs strict checks on overprefetch, underprefetch, and the relative order in which fetch and prefetches must occur.
