论文摘要
我们提出了一个专门的获奖者全部电路，以有效地实施层次内记忆中细胞之间的列内竞争，这是该算法的关键部分。所有输入和输出都是基于电荷的，以与标准CMOS兼容。该电路结合了竞争优势的备忘录，以模拟具有预测状态的单元的色谱柱。该电路还可以通过被动平均和比较单元输出来检测列“爆发”。彻底描述了所提出的自旋设备和电路，并使用一系列模拟来预测性能。模拟表明，该电路可以在15 ns以下的9个输入竞争操作完成，成本约为25 pj。
We propose a dedicated winner-take-all circuit to efficiently implement the intra-column competition between cells in Hierarchical Temporal Memory which is a crucial part of the algorithm. All inputs and outputs are charge-based for compatibility with standard CMOS. The circuit incorporates memristors for competitive advantage to emulate a column with a cell in a predictive state. The circuit can also detect columns 'bursting' by passive averaging and comparison of the cell outputs. The proposed spintronic devices and circuit are thoroughly described and a series of simulations are used to predict the performance. The simulations indicate that the circuit can complete a nine-cell, nine-input competition operation in under 15 ns at a cost of about 25 pJ.
