摘要： Systems and methods pertain to a method of memory management. Gaps are unused portions of a physical memory in sections of the physical memory mapped to virtual addresses by entries of a translation look-aside buffer (TLB). Sizes and alignment of the sections in the physical memory may be based on the number of entries in the TLB, which leads to the gaps. One or more gaps identified in the physical memory are reclaimed or reused, where the one or more gaps are collected to form a dynamic buffer, by mapping physical addresses of the gaps to virtual addresses of the dynamic buffer.

摘要： Systems, methods, and computer programs are disclosed for adaptive compression-based demand paging. Two or more compressed software image segments are stored in each of one or more memories. Each compressed software image segment corresponds to at least one software task and includes one or more pages that are compressed in accordance with a compression characteristic different from that of the other software image segments. If it is determined that a page request associated with an executing software task identifies a page that is not stored in the system memory, then a portion of the compressed software image segment containing the identified page is decompressed, and the decompressed page is stored in the system memory.

摘要： Methods and apparatus are provided for device configuration (e.g., feature segment loading and system selection). Certain aspects of the present disclosure generally relate to operating a user equipment (UE) in a first radio access network (RAN) with a first set of modem features that supports the first RAN, detecting a second RAN not supported by the first set of modem features, and rebooting the modem software to load a second set of modem features that supports the detected RAN. For certain aspects, the first RAN may be a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network and the second RAN may be a Wideband-Code Division Multiple Access (W-CDMA) network or long term evolution network. This allows features to be loaded into memory (e.g., only) when they are required to support a detected RAN, rather than loading an entire image, thereby conserving DRAM and increasing efficiency.

摘要： A method, an apparatus, and a computer program product for transport protocol communications processing are provided. The apparatus may be an electronic device. The electronic device receives a transport protocol communications from a sender device. The electronic device generates a plurality of acknowledgments in response to the received transport protocol traffic and stores the plurality of acknowledgments at a first memory. A modem load for a modem of the electronic device is determined. The electronic device identifies the plurality of acknowledgments to identify a subset of the plurality of acknowledgments in response to the determined modem load satisfying a modem load threshold condition. The electronic device moves the subset of acknowledgments from the first memory to a second memory. The electronic device transmits the subset of acknowledgments to the sender device.

摘要： Aspects include computing devices, systems, and methods for implementing executing decompression of a compressed page. A computing device may determine a decompression block belonging to a compressed page that contains a code instruction requested in a memory access request. Decompression blocks, other than the decompression block containing the requested code instruction, may be selected for decompression based on their locality with respect to the decompression block containing the requested code instruction. Decompression blocks not identified for decompression may be substituted for a fault or exception code. The computing device may decompress decompression blocks identified for decompression, terminating the decompression of the compressed page upon filling all blocks with decompressed blocks, faults, or exception code. The remaining decompression blocks belonging to the compressed page may be decompressed after or concurrently with the execution of the requested code instruction.

摘要： Aspects include computing devices, systems, and methods for implementing executing decompression of a compressed page. A computing device may determine a decompression block of a compressed page that contains a code instruction requested in a memory access request. Decompression blocks, other than the decompression block containing the requested code instruction, may be selected for decompression based on being situated between an end of the compressed page and the decompression block containing the requested code instruction. Decompression blocks not identified for decompression may be substituted for a fault or exception code. The computing device may decompress decompression blocks identified for decompression, starting at the end of the compressed page and terminating the decompression of the compressed page upon filling all blocks with decompressed blocks, faults, or exception code. The remaining decompression blocks of the compressed page may be decompressed after or concurrently with the execution of the requested code instruction.
