A Simulation Study of Decoupled Architecture Computers

Smith, Weiss, Pang
1986 IEEE transactions on computers  
Decoupled architectures achieve high scalar performance by cleanly splitting instruction processing into memory access and execution tasks.  ...  We first describe a decoupled architecture based on the CRAY-1 scalar architecture. The sensitivity to memory access delays are studied by varying memory access time over a wide range o,f yalues.  ...  This is because vector architectures and decoupled architectures are in a sense orthogonal (one could use both in the same computer).  ...

2020 arXiv   pre-print
More specifically, we introduce a novel architecture controlling module in each layer to encode the network architecture by a vector.  ...  Furthermore, to improve the interpretability and compactness of the decoupled network, the output of each layer is encoded to align the architecture encoding vector with the constraint of sparsity regularization  ...  Network Training We expect the network architecture to be gradually decoupled during training, where the essential problem is how to learn an architecture encoding vector that fits the data distribution  ...
