摘要： 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.

摘要： A de-interleaver generates a plurality of De-interleaved Reorder Physical (DRP) addresses to simultaneously write a corresponding plurality of LLR values into a multi-banked memory such that not more than one LLR value is written into each bank of the multi-banked memory at a time. A sequence of such parallel writes results in the LLR values of a transmission of a sub-packet being stored in the memory. Address translation performed during generation of the DRP addresses causes the LLR values to be stored within the banks such that a decoder can read LLR values out of the memory in a de-interleaved sequence. Each memory location of a bank is a word-location for storing multiple related LLR values, where one LLR value is stored along with its parity values. The ability to simultaneously write to multiple LLR values is used to clear locations in a fast and efficient manner.
