Patent CA-2656235-A1 (CA)
Title: Methods and devices for the discrete self-adjusting controllers
Inventor: VU KY M
IPC: G05B13/00
Filed: 2009-02-16
Abstract: Methods to adjust the controller's gains of a discrete controller are suggested.  The adjustment relies on a set of parameters called the state parameters.  These parameters are combinations of modes, which propagate the deviation from minimum variance control and contribute to more variability of the error variable. The state parameters are re-estimated on-line to portray the real current behavior of the control system, and this re-estimation establishes the self-adjusting algorithm. The algorithm can be used for both adaptive and self-tuning controls. In a nonadaptive environment, the state parameters converge to constant values. In an adaptive environment, the state parameters adapt to new values.

Patent CA-2674723-A1 (CA)
Inventor: DIEFFENDERFER JAMES NORRIS
IPC: G06F12/08
Filed: 2008-01-28
Abstract: A snoop request cache maintains records of previously issued snoop requests. Upon writing shared data, a snooping entity performs a lookup in the cache. If the lookup hits (and, in some embodiments, includes an identification of a target processor) the snooping entity suppresses the snoop request. If the lookup misses (or hits but the hitting entry lacks an identification of the target processor) the snooping entity allocates an entry in the cache (or sets an identification of the target processor) and directs a snoop request such to the target processor, to change the state of a corresponding line in the processor's L1 cache. When the processor reads shared data, it performs a snoop cache request lookup, and invalidates a hitting entry in the event of a hit (or clears it processor identification from the hitting entry), so that other snooping entities will not suppress snoop requests to it.
