Abstract: Methods for determining a fixed point format for one or more layers of a DNN based on the portion of the output error of the DNN attributed to the fixed point formats of the different layers. Specifically, in the methods described herein the output error of a DNN attributable to the quantisation of the weights or input data values of each layer is determined using a Taylor approximation and the fixed point number format of one or more layers is adjusted based on the attribution. For example, where the fixed point number formats used by a DNN comprises an exponent and a mantissa bit length, the mantissa bit length of the layer allocated the lowest portion of the output error may be reduced, or the mantissa bit length of the layer allocated the highest portion of the output error may be increased. Such a method may be iteratively repeated to determine an optimum set of fixed point number formats for the layers of a DNN.

If errors occur during the fabrication of the AM products, individual AM devices are able to create and implement solutions that solve fabrication errors and communicate that data with the other AM devices for present and future AM fabrication efforts.

Abstract: Simulation processing is performed on a host apparatus in respective time periods to simulate operation of simulated agents of a target apparatus. During each time period, the simulation processing exclusively simulates operation of a single simulated agent. When the target program code processed in a current time period allocated for simulation of a given simulated agent includes a transaction start instruction representing a start of a transaction comprising instructions executed between the transaction start instruction and a transaction end instruction for which effects of the instructions of the transaction are to be committed when the transaction end instruction is reached in the absence of the transaction being aborted, it is detected whether the current time period ends before the transaction end instruction of the transaction is reached, and if so the transaction is aborted. This enables a correct transaction behaviour to be simulated without requiring memory conflict checking.
