1. A computing system comprising:
a data input configured to receive an input data signal;
a computation unit having an input coupled with the data input, the computation unit being operative to apply a weight to an input data signal received at its input to generate a weighted output signal; and
a controller;
wherein the controller is configured to monitor a parameter of the input data signal and/or a parameter of the weighted output signal and to issue a control signal to the computation unit to control a level of accuracy of the weighted output signal based at least in part on the monitored parameter; and
wherein the computation unit is a digital computation unit configured to perform bit-series computation of bits of the input data signal and the weight.
