1. A neural network operation apparatus, comprising:
a receiver configured to receive a first input feature map;
a controller configured to control multiplier-accumulators (MACs) included in a first MAC array by setting an operation state of one MAC in the first MAC array to an enable state and setting an operation state of remaining MACs in the first MAC array to a disable state; and
a first operation engine comprising the first MAC array and configured to process the first input feature map based on the MACs of which operation states are controlled.
