Methods, systems and apparatus for adjusting duty cycle of pulse width modulated (PWM) waveforms

Patent Gallegos-Lopez, Gabriel; Kinoshita, Michael H; Ransom, Ray M; ...

Embodiments of the present invention relate to methods, systems and apparatus for controlling operation of a multi-phase machine in a vector controlled motor drive system when the multi-phase machine operates in an overmodulation region. The disclosed embodiments provide a mechanism for adjusting a duty cycle of PWM waveforms so that the correct phase voltage command signals are applied at the angle transitions. This can reduce variations/errors in the phase voltage command signals applied to the multi-phase machine so that phase current may be properly regulated thus reducing current/torque oscillation, which can in turn improve machine efficiency and performance, as wellmore » « less

Method and apparatus for using compression to improve performance of low voltage caches

Patent Kalamatianos, John; Ganapathy, Shrikanth; Das, Shomit N.; ...

A method of operating a cache in a computing device includes, in response to receiving a memory access request at the cache, determining compressibility of data specified by the request, selecting in the cache a destination portion for storing the data based on the compressibility of the data and a persistent fault history of the destination portion, and storing a compressed copy of the data in a non-faulted subportion of the destination portion, wherein the persistent fault history indicates that the non-faulted subportion excludes any persistent faults.
