    • A flexible and reconfigurable digital system (for example, a wireless modem) includes a set of sub-circuits. Each sub-circuit includes a task manager and an amount of configurable hardware circuitry for performing a type of operation on a data stream. The task manager of a sub-circuit can configure and control the configurable hardware of the sub-circuit. A central processor configures and orchestrates operation of the sub-circuits by maintaining a set of task lists in a tightly coupled memory. Each task list includes task instructions for a corresponding sub-circuit. The task manager of a sub-circuit reads task instructions from its task list and controls its associated hardware circuitry as directed by the instructions. A timestamp task instruction and a push task instruction and the task list architecture allow modem sub-circuits to be easily reconfigured to operate in accordance with either a first air interface standard or a second air interface standard.
    • 灵活和可重新配置的数字系统(例如,无线调制解调器)包括一组子电路。 每个子电路包括任务管理器和用于对数据流执行一种操作的可配置硬件电路的量。 子电路的任务管理器可以配置和控制子电路的可配置硬件。 中央处理器通过在紧耦合存储器中维护一组任务列表来配置和协调子电路的操作。 每个任务列表包括相应子电路的任务指令。 子电路的任务管理器从其任务列表读取任务指令,并根据指令控制其相关联的硬件电路。 时间戳任务指令和推送任务指令以及任务列表架构允许将调制解调器子电路轻松地重新配置为根据第一空中接口标准或第二空中接口标准进行操作。

    • A modem (for example, a modem within a cellular telephone) includes a plurality of Wireless Communication System Modem Sub-Circuits (WCSMSCs). Each WCSMSC receives a control signal generated by a corresponding one of a plurality of programmable timers. Each timer receives the same sequence of count values from a wall clock counter. A processor that controls overall modem operation can program a timer to generate a control pulse at a particular count time of the wall clock counter. The processor can also program a timer to generate a periodic control signal. The control signals output from the timers orchestrate when the various WCSMSCs start operating in the processing of a frame. By virtue of the programmability of the timers, the wall clock timer system is programmable to generate customized control signals such that frames of new and different protocols having arbitrary frame structures can be processed by the same modem/timer system.
    • 调制解调器(例如,蜂窝电话中的调制解调器)包括多个无线通信系统调制解调器子电路(WCSMSC)。 每个WCSMSC接收由多个可编程定时器中相应的一个产生的控制信号。 每个定时器从挂钟计数器接收相同的计数值序列。 控制整个调制解调器操作的处理器可以编程定时器以在挂钟计数器的特定计数时间产生控制脉冲。 处理器还可以编程定时器以产生周期性控制信号。 当各种WCSMSC在帧的处理中开始运行时,从定时器输出的控制信号协调编排。 通过定时器的可编程性,挂钟计时器系统可编程以产生定制的控制信号,使得具有任意帧结构的新协议和不同协议的帧可以由相同的调制解调器/定时器系统来处理。
