Abstract: A method and a MAC unit that may include accumulation unit and a multiplier. A accumulation unit that includes a first part, a second part and a third part. The first part may calculate a truncated sum. The second part may be configured to (a) receive, during each calculation cycle, a carry out of an add operation performed during a calculation cycle, (b) receive a sign bit of an intermediate product calculated during the calculation cycle; and (c) calculate, by the counter logic, a counter logic value, and (d) convert, after a start of a last calculation cycle of the calculation cycles, an output value of the counter logic to an intermediate value having a two's complement format. The third part may be configured to calculate an output value of the MAC unit based on the intermediate value and a truncated sum calculated by the first part of the accumulation unit.

Abstract: A method for adjusting a pruned neural network, the method may include adjusting weights of the pruned neural network to provide an adjusted neural network. The pruned neural network was generated by a pruning process and is associated with pruning related weights. The pruning related weights include survived weights and erased weights. A survived weight was assigned a non-zero value by the pruning process. An erased weight was assigned a zero value by the pruning process. The adjusting may include setting values of some of the adjusted weights based on values of at least one of the pruning related weights.

Abstract: A method for monitoring, the method may include constantly operating, within one or more sensing periods, a microphone and a trigger sensor of a monitor that is installed in a vehicle, even when an processor of the monitor is asleep; receiving by the microphone, while the processor is asleep, initial audio signals; converting the initial audio signals to initial electrical signals representative of the initial audio signals; searching, by the trigger sensor and in the initial electrical signals, for a voice trigger that is related to a sound made by the baby; when finding the voice trigger then awakening the processor; searching, by the processor, for the sound made by the baby in at least one out of the initial audio signals, and following audio signals. When finding the sound made by the baby then executing a baby in vehicle response.
