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.
