Once the output of a processed neuron is obtained, it is crossed through the activation function and the result is stored in the data row, in the cell pointed by the current microinstruction.
However, by adding the register-level microinstruction activity, the actual CPU implementation of the Fetch is more clearly understood.
1992] another approach for more accurate timing is proposed; the resulting tool was able to analyze microinstruction streams using machine description rules, and thus it was retargetable to various architectures.
During an instruction cycle, the local control unit of a module selects a parallel microinstruction and each FU receives its part.
Microcode requires a two-level decode [19] (instructions need to be decoded into microinstructions, and then decoded and executed), and microcoded machines tend to be slower than hardwired ones.
