Methods and apparatuses involving radar system data paths

A radar data acquisition apparatus for use with sensor circuitry, including multiple radar sensors, to provide sensor data via multiple virtual channels and multiple data types, and to receive configuration data useful for configuring the multiple radar sensors, the apparatus comprising:

• a memory circuit having a plurality of buffers;
• a bus-interface circuit to control bus interconnects for bus communications involving a radar signal transmitter and the memory circuit;
• and
• a radar signal receiving circuit to receive radar signals and including data acquisition path circuitry with multiple circuit paths to process streams of data in response to the sensor circuitry, and further including a receive-side master controller to:
• convey data, via the bus-interface circuit, to the plurality of buffers of the memory circuit for supporting the sensor data via the multiple virtual channels and the multiple data types;
• and
• generate a plurality of selectable-type transactions to be linked in selected ones of the plurality of buffers, in response to the data provided from the sensor circuitry and based on the sensor data being provided via different ones of the multiple virtual channels and of the multiple data types,
• wherein one or more data-processing efficiency parameters are associated with data throughput pertaining to at least one of:
• bandwidth or use of one or more computer processors integrated within the apparatus, cache-processing availability, debug-tracing bandwidth relating to the bus-interface circuit, and switching capabilities of the bus-interface circuit.
