Abstract: Various embodiments of methods and systems for deep coalescing memory management (“DCMM”) in a portable computing device (“PCD”) are disclosed. Because multiple active multimedia (“MM”) clients running on the PCD may generate a random stream of mixed read and write requests associated with data stored at non-contiguous addresses in a double data rate (“DDR”) memory component, DCMM solutions triage the requests into dedicated deep coalescing (“DC”) cache buffers, sequentially ordering the requests and/or the DC buffers based on associated addresses for the data in the DDR, to optimize read and write transactions from and to the DDR memory component in blocks of contiguous data addresses.

Abstract: Systems and methods are disclosed for providing multi-user power saving codebook optimization. One such method comprises: generating a unique codebook for a plurality of computing devices, each unique codebook configured for encoding memory data in the corresponding computing device; providing the unique codebooks to the corresponding computing devices via a communications networks; receiving compression statistics from one or more of the computing devices via the communications network, the compression statistics related to the corresponding unique codebook; and generating an optimized codebook for at least one of the computing devices based on the received compression statistics.

Abstract: Systems and methods are disclosed for providing memory channel interleaving with selective power or performance optimization. One such method involves configuring a memory address map for two or more memory devices accessed via two or more respective memory channels with an interleaved region and a linear region. The interleaved region comprises an interleaved address space for relatively higher performance use cases. The linear region comprises a linear address space for relatively lower power use cases. Memory requests are received from one or more clients. The memory requests comprise a preference for power savings or performance. Received memory requests are assigned to the linear region or the interleaved region according to the preference for power savings or performance.
