Abstract: An intelligent tile-based memory bandwidth management solution executed by an address aperture, such as a compression address aperture, services linearly addressed data requests (read requests and write requests) from a processor to data stored in a memory component having a tile-based address structure. For read requests, the aperture stores previously read tiles (full or partial) in a tile-aware cache and then seeks to service future read requests from the cache instead of the long-term memory component. For write requests, the aperture stores the write data in the tile-aware cache and assembles the data with write data from other write requests so that full tile data writes to the long-term memory may be achieved in lieu of excessive partial-tile writes.

Abstract: Techniques for preventing circumvention of digital rights management protections on electronic content are provided. A method according to these techniques includes receiving a content stream, obtaining samples from the content stream, generating a histogram based on the samples from the content stream, classifying the content stream as including audio content or non-audio content based on the histogram, and modifying portions of the content stream responsive to classifying the content stream as including non-audio content. The content stream can be modified such that any video content included in the content stream would be rendered unplayable, while audio content included in the content stream remains playable.

Abstract: Systems and methods for adaptive compression mode selection for memory buffers such as those used in or with a portable computing device (“PCD”) are presented. During operation of the PCD a first compression mode is selected for a buffer and the buffer is formatted to the first compression mode. Any access to the buffer by a component of the PCD, core of the PCD or software application running on the PCD is monitored. Based on the amount and/or type of access to the buffer, a second compression mode for the buffer is selected. The buffer is formatted to the second compression mode, providing a cost effective ability to adaptively format buffers based on the component(s), cores(s), and/or software application(s) accessing the buffers, and allowing for improving or optimizing bandwidth, memory footprint, resource conflict, power consumption, latency, and/or performance of component(s), core(s), or software application(s) accessing buffers as desired.
