Abstract: Multi-step programming of heat-sensitive non-volatile memory (NVM) in processor-based systems, and related methods and systems are disclosed. To avoid relying on programmed instructions stored in heat-sensitive NVM during fabrication, wherein the programmed instructions can become corrupted during thermal packaging processes, the NVM is programmed in a multi-step programming process. In a first programming step, a boot loader comprising programming instructions is loaded into the NVM. The boot loader may be loaded into the NVM after the thermal processes during packaging are completed to avoid risking data corruption in the boot loader. Thereafter, the programmed image can be loaded quickly into a NV program memory over the peripheral interface using the boot loader to save programming time and associated costs, as opposed to loading the programmed image using lower transfer rate programming techniques. The processor can execute the program instructions to carry out tasks in the processor-based system.

Abstract translation: 公开了基于处理器的系统中的热敏非易失性存储器（NVM）的多步编程以及相关的方法和系统。 为了避免在制造期间依赖于存储在热敏NVM中的编程指令，其中编程指令可能在热封装过程中被破坏，NVM以多步编程过程编程。 在第一编程步骤中，包括编程指令的引导加载器被加载到NVM中。 引导加载程序可能在打包完成后的热处理后加载到NVM中，以避免引导加载程序中的数据损坏风险。 此后，与使用较低传输速率编程技术加载编程图像相比，编程图像可以使用引导加载程序通过外设接口快速加载到NV程序存储器中，从而节省编程时间和相关成本。 处理器可以执行程序指令以在基于处理器的系统中执行任务。

Abstract: Various apparatuses and methods for transmitting uplink data of an application at a user equipment are provided. In one aspect of the disclosure, uplink data of an application at a user equipment (UE) is transmitted to a network. A first amount of the uplink data expected to be buffered at a radio link control (RLC) layer is determined based on a latency of the application. A second amount of the uplink data available for transmission at the RLC layer is determined based on information provided by a modem of the UE. A data rate of the application is dynamically adjusted based on a difference between the first amount and second amount of the uplink data. In another aspect of the disclosure, an amount of the application data buffered at the RLC layer is maintained to be greater than a predetermined threshold that sets a Happy bit at an unhappy setting. The unhappy setting is communicated to the network, a data rate of the application is increased in response to an increased grant from the network due to the unhappy setting. In another aspect of the disclosure, a maximum modem supported data rate at which the user equipment (UE) transmits uplink data of an application is determined based on an uplink channel capacity estimate, a modem queue length estimate, a codec rate change frequency of the application, and a delay threshold of the modem queue.

Abstract: Systems and methods for controlling a modem in a computing device are disclosed. In one embodiment, a traffic scheduler is logically positioned between the applications and the net driver of the computing device. The traffic scheduler receives all the packets from the applications and prioritizes the packets in a smart queue. Based on the available uplink bandwidth and/or the queue at the modem, the traffic scheduler passes packets from the smart queue to the net driver to be passed to the modem. In addition to having the benefit of having the higher priority packets be passed before the lower priority packets, the traffic scheduler has the added advantage of allowing the deletion of packets that are no longer needed (e.g., packets generated by a program that the user has closed).
