The Combined addressing of Microinstructions is used in Micro-Programmed logic devices because it is a convenient and easy way of writing the MicroPrograms as well as the small size of the microinstruction [6, 9, 10].
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. This procedure is illustrated in Fig.
d) 16 microinstructions. The pendulum runs: a) in the Virtex at 21 MHz, 131 K FIPS and 64 MFRPS.
As you can see from the comments to the right of each microinstruction, the Little Man idea is maintained.
[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.
The latter represents a sequence of parallel microinstructions with separate fields for each FU.
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.
