我们描述了一个新的计划，异步通信的信息出二维处理阵列。我们的架构采用模拟赢家采取所有（WTA）电路，而不是在其他设计中发现的数字二叉树仲裁器。一个小的系统，结合了一个阵列的9/spl倍/12像素已制造在2/spl μ/，双多晶硅，双金属工艺。实验结果验证了系统的功能与完整的握手通信周期为3 /spl μ/s。WTA电路已经过独立测试，其运行验证低至18 ns。
We describe a novel scheme for asynchronous communication of information out of two dimensional processing arrays. Our architecture employs analog Winner Takes All (WTA) circuits instead of digital binary-tree arbiters found in other designs. A small system that incorporates an array of 9/spl times/12 pixels has been fabricated in a 2/spl mu/, double polysilicon, double metal process. Experimental results verify system functionality with a full-handshaking communication cycle of 3 /spl mu/s. The WTA circuits have been independently tested and their operation verified down to 18 ns.
