Abstract: Certain embodiments of the present disclosure propose a technique that may be utilized to accelerate the processing of MAC management messages by an MS, allowing the MS to return to a lower power state sooner, thereby conserving power. An indication of whether or not data bursts in a downlink (DL) sub-frame contain MAC management messages may allow the MS to avoid needlessly processing of data bursts and return to a low power state sooner.

Abstract: A memory system includes a status circuit having a common status node electrically connected to a respective status pad of each of a plurality of memory chips. The memory system also includes a plurality of resistors disposed within the status circuit to define a voltage divider network for generating different voltage levels at the common status node. Each of the different voltage levels indicates a particular operational state combination of the plurality of memory chips. Also, each of the plurality of memory chips is either in a first operational state or a second operational state. Additionally, the different voltage levels are distributed within a voltage range extending from a power supply voltage level to a reference ground voltage level.

Abstract: Certain embodiments of the present disclosure control whether or not certain protocol stack operation are performed in a hardware (HW) protocol stack accelerator based on ARQ/HARQ re-transmission rate. Latency penalties associated with using the HW accelerator are typically higher than the data movement overhead when this data does not need to be processed by the HW accelerator, such as when a re-transmission error occurs. According to certain embodiments, the HW accelerator is activated if the ARQ/HARQ re-transmission rate is below a threshold value. Otherwise, if the ARQ/HARQ re-transmission rate is above a threshold, at least a portion of the HW accelerator may be de-activated, which may reduce overhead associated with moving data between the protocol stack and the HW accelerator.

Abstract translation: 本公开的某些实施例基于ARQ / HARQ重传速率来控制是否在硬件（HW）协议栈加速器中执行某些协议栈操作。 当HW数据不需要由HW加速器处理时，例如当发生重传错误时，与使用HW加速器相关联的延迟处罚通常高于数据移动开销。 根据某些实施例，如果ARQ / HARQ重传率低于阈值，则HW加速器被激活。 否则，如果ARQ / HARQ重传速率高于阈值，那么硬件加速器的至少一部分可以被去激活，这可以减少与在协议栈和HW加速器之间的移动数据相关联的开销。
