Abstract
A cellular modem processor can include dedicated processing engines that implement specific, complex data processing operations. The processing engines can be arranged in pipelines, with different processing engines executing different steps in a sequence of operations. Flow control or data synchronization between pipeline stages can be provided using a hybrid of firmware-based flow control and hardware-based data dependency management. Firmware instructions can define data flow by reference to a virtual address space associated with pipeline buffers. A hardware interlock controller within the pipeline can track and enforce the data dependencies for the pipeline.
