查询词典 binary digit

The ADC is pipelined, including a single-input/difference-output sample/hold circuit and nine stage subcircuits. The preceding eight stages are 1.5bits/stage, and the last stage consists of two comparators. Every input sample is converted into 18 bits binary signals, and these binary signals are converted into 10 bits binary signals through digital correction circuit.

This model uses nonlinear mapping to map samples into high dimensional feature space, and compares the distribution of each type of samples in the high dimensional space. So that a binary decision tree is constructed through clustering, which can make the more separable classes classified at the upper node of the binary decision tree. The model overcomes the accumulation of misclassification and avoids the condition of impartibility efficiently. At the same time, each node of decision tree uses binary least squares wavelet support vector machine to obtain higher generalization ability.

该模型利用非线性映射将样本投影到高维特征空间，比较每类样本在高维空间的分布情况，进行聚类构造出一个二叉决策树，使容易区分的类别从根节点逐层分类出来，有效克服了错分积累和避免不可分情况；同时，各个节点采用二值最小二乘小波支持向量机，以获得较高的泛化能力。

In datapath extraction, we build the environments for all datapath units by making assignments to the Boolean interface variables and some word variables. Binary CSP modeling then translates the RTL datapath satisfiability problem to a binary CSP description, which in turn will be sent to a binary CSP engine and solved by conflict-directed backjumping search strategy. The answer will be either a witness of satisfiable instance or a unsatisfiable decision.
