Assignee: MICRON TECHNOLOGY, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 10:
11. A device, comprising:
a radar, having:
random access memory;
a circuit configured to generate data representative of a radar image based on reflections of electromagnetic waves and write the data to the random access memory as an input to an artificial neural network;
a field-programmable gate array (FPGA) or application specific integrated circuit (ASIC) having:
a memory interface to access the random access memory; and
at least one processing unit configured to execute instructions having matrix operands to implement computations of the artificial neural network, the artificial neural network configured to identify one or more features in the radar image in an output;

an image sensor configured in an integrated circuit device containing the random access memory; and
a host interface configured to output, to a host system, data representative of attributes of the one or more features;

wherein the image sensor is configured to:
capture an optical image of a scene corresponding to the radar image; and
write data representative of the optical image into the random access memory of the radar as part of the input to the artificial neural network;

wherein the circuit is configured to write the data representative of the radar image into the random access memory of the radar as part of the input to the artificial neural network in parallel with the image sensor writing of the data representative of the optical image into the random access memory; and
wherein the radar is configured to:
store the input in the random access memory of the radar for a predetermined period of time after transmission of the data representative of the representative of attributes the host system;
receive, within the predetermined period of time, a request from the host system;
transmit the input to the host system; and
erase the input from the radar after the predetermined period of time.
