Abstract: The present disclosure provides for adaptive scheduling of memory refreshes. One embodiment relates to a method of adapting an initial refresh sequence. In this method, flow and blockage scores for each refresh sequence of a plurality of refresh sequences are obtained and stored in an array of scores. An initial refresh sequence is selected in a way that favors a high flow score and a low blockage score. Another embodiment relates to a method of adapting a current refresh sequence. Current flow and blockage scores are obtained and stored for the current refresh sequence. The current flow and blockage scores are used to update (by averaging, for example) the existing flow and blockage scores for the current refresh sequence. The next refresh sequence is then chosen from amongst a plurality of refresh sequences in a way that favors a high flow score and a low blockage score.

Abstract: Methods and apparatus for managing sideband routers in an On-Die System Fabric (OSF) are described. In one embodiment, a sideband OSF router is configurable during runtime based, at least in part, on information stored in a table accessible by an agent coupled to the sideband OSF router. Other embodiments are also disclosed.

Abstract: Methods and apparatus for managing sideband segments in an On-Die System Fabric (OSF) are described. In one embodiment, a sideband OSF includes a plurality of segments that may be reset or powered down independently after power management logic determines that in progress messages have been handled and future messages to the segment being reset or powered down will be blocked. Other embodiments are also disclosed.

Abstract: An optical encoder includes a coding element having a track with multiple transparent sections, a light source positioned to output light to the track, and a photodetector array, positioned to detect light that passes through the transparent sections of the track. The photodetectors of the photodetector array have larger width dimensions than the width dimensions of the transparent sections of the track. Resolution of the optical encoder may be adjusted by changing the resolution of the coding element.
