Abstract: An integrated circuit may include multiple instances of a component (e.g. a processor) and a control circuit. The instances may be configured to operate in various modes. Some of the modes are incapable of presenting a worst-case load on the power supply. The control circuit may be configured to monitor the instances and detect the modes in which the instances are operating. Based on the monitoring, the control circuit may request to recover a portion of the voltage margin established for worst-case conditions in the instances.

Abstract: In an embodiment, an integrated circuit includes multiple instances of a component (e.g. a processor) and a control circuit. The instances may be configured to operate in various modes. Some of the modes are incapable of presenting a worst-case load on the power supply. The control circuit may be configured to monitor the instances and detect the modes in which the instances are operating. Based on the monitoring, the control circuit may request to recover a portion of the voltage margin established for worst-case conditions in the instances. If the instances are to change modes, they may be configured to request mode change from the control circuit. If the mode change causes an increase in the current supply voltage magnitude (e.g. to restore some of the recovered voltage margin), the control circuit may cause the restore and permit it to complete prior to granting the mode change.

Abstract: In an embodiment, an integrated circuit includes a first circuit and a characterization circuit to capture a histogram of the supply voltage magnitude to the first circuit (or other characteristics of the first circuit). In various embodiments, the characterization circuit may: be located near the first circuit; include a sample/hold circuit that may sample the supply voltage in a short window of time and an ADC that is configured to converge to the sampled voltage over multiple orders of magnitude longer than the short window; be relatively small and low power; capture multiple histograms, e.g. one for each mode of the first circuit; support a blackout interval during mode changes; support a zoom feature to a subrange of supply voltage disabled with fine-grain histogram buckets; and/or include one or more comparators to detect maximum and/or minimum voltages experienced over a time interval.

Abstract: In an embodiment, an integrated circuit comprises a decrypt unit configured to decrypt an encrypted, compressed video stream; an on-chip buffer; and a decompressor coupled to the decrypt unit and the on-chip buffer. The decompressor is configured decompress the video stream, and to store a first portion of each of a first plurality of frames decompressed from the video stream in the on-chip buffer. The decompressor is further configured to store a remaining portion of each of the first plurality of frames in an external memory, wherein each frame as stored in the external memory is incomplete because the first portion is not stored in the external memory.
