1. A radar monolithic microwave integrated circuit (MMIC), comprising:
at least one of a transmit channel for transmitting radar signals or a receive channel for receiving reflected radar signals;
a communication interface configured to sequentially receive a plurality of downloadable programming contexts from an external controller, wherein each downloadable programming context comprises a respective program and associated data;
a random-access memory (RAM) comprising a plurality of partitions configured to sequentially store the plurality of downloadable programming contexts that are received from the external controller, wherein each subsequent downloadable programming context received from the external controller is stored in a different partition than a partition used to store a most-recent downloadable programming context received from the external controller; and
a configuration and sequencing circuit configured to:
sequentially activate and deactivate the plurality of downloadable programming contexts according to a context execution sequence, and
execute an activated downloadable programming context stored in a corresponding partition of the plurality of partitions,
wherein the communication interface is configured to receive, and the RAM is configured to store, a subsequent downloadable programming context prior to a time slot in the context execution sequence that is assigned to the subsequent downloadable programming context.
