在设计中,常常为了控制是否需要正常译码,在Decoder输入端加入一个使能端,用于控制是否正常进行译码,下图是带有使能端的3line-8line译码器,当使能端位高电平时,该译码器电路进行正常工作,反之译码器输出端都为无效信号; gate-level 3line-8line Decoder with enable input 使能端(enable)在组合逻辑电路中有时非常方便...

with at least one of the N-channel transistors which is controlled by the true of the inputs, A0, A1, A2, or A3. Since the inputs A0 through A3 were assumed to be in a low state, they will not enable any of the transistors they control, and therefore, only one path is completed...
Therefore, based on an encoder-decoder architecture, we propose a novel alternate encoder dual decoder CNN-Transformer network, AD2Former, with two attractive designs: 1) We propose alternating learning encoder can achieve real-time interaction between local and global information, allowing both to ...
Hence, it is mathematically justified to integrate the HAT model with an external LM using the density ratio method. In [181], an internal LM estimation (ILME)-based fusion was proposed to enable a more effective LM inte- gration. During inference, the internal LM score of an E2E model ...
There are two inputs A and B, which acts as control inputs for the decoder circuit. Many decoder circuits are designed with an enable signal which is set to high when the decoder performs its operation.Inputs Outputs A B Z0 Z1 Z2 Z3 0 0 1 0 0 0 0 1 0 1 0 0 1 0 0 0 1...
