Abstract:
An autonomous hardwired tracking loop (HWTL) integrated circuit comprising a HWt coprocessor coupled to receive an IF signal from a correlator engine, the HWTL coprocessor providing radio signal processing comprising data tracking or acquisition processing on the IF Signal to generate HWTL processed data for further radio receiver processing operations by a CPU wherein the HWTL coprocessor comprises:a track state module (TRKSTATE) that initiates a set of state machine operations, and also provides a plurality of functional control signals of the HWTL coprocessor comprising one or more select and enabled lines; andan arithmetic logic unit (ALU) coupled to the TRKSTATE module to receive the one or more select and enable signal to provide a plurality of data path calculations for tracking, the ALU is also coupled to the one or more on-board memory components for retrieving and storing a set of processed data.
