摘要： A flexible and reconfϊgurable 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.
