Title:
METHOD FOR SELECTING CALCULATION BIT WIDTH OF MULTI-BIT WIDTH PE ARRAY AND CALCULATION PRECISION CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/047215
Kind Code:
A1
Abstract:
A method for selecting a calculation bit width of a multi-bit width processing element (PE) array and a calculation precision control circuit. A probability value outputted by a last Softmax layer of a neural network is analyzed to determine the magnitude of the outputted maximum probability so as to evaluate network recognition precision; and it is determined, by means of two set probability thresholds, whether the outputted maximum probability value satisfies the requirement of calculation precision, wherein if the maximum probability value is less than the minimum threshold, a signal of a high bit width PE array is used, if the maximum probability value is greater than the minimum threshold and less than the maximum threshold, the previous bit width PE array is maintained, and if the maximum probability value is greater than the maximum threshold, a signal of a low bit width PE array is used, so that the maximum probability outputted by the network is maintained within a certain range, thereby reducing power consumption while ensuring the recognition precision of the network.
