Claim 3:
4. The apparatus of claim 2, wherein the sensor compute circuit comprises:
a compute memory configured to store: input data to a neural network layer of the neural network, weight data of the neural network layer, and intermediate output data of the neural network layer;
a data processing circuit configured to perform arithmetic operations of the neural network layer on the input data and the weight data to generate the intermediate output data; and
a compute controller configured to:
fetch, from the compute memory, a first subset of the input data and a first subset of the weight data corresponding to the first subset of the input data, the first subset of the input data corresponding to at least some of the first active pixels;
control the data processing circuit to perform the arithmetic operations on the first subset of the input data and the first subset of the weight data to generate a first subset of the intermediate output data for the first image frame, the first subset of the intermediate output data corresponding to the first subset of the input data;
store the first subset of the intermediate output data for the first image frame in the compute memory; and
store a predetermined value for a second subset of the intermediate output data for the first image frame in the compute memory, the second subset of the intermediate output data corresponding to the first inactive pixels.
