摘要
胚胎型仿生电路是一种芯片级容错数字电路,其工作机制为汲取生物体生长过程的灵感从而使得数字系统具有自主容错能力。该电路是由二维电子细胞阵列组成,文中分析了这种数字电路的结构和容错机制,讨论了细胞的主要组成部件的设计,并基于海明码(Hamming Code)为细胞中的存储器设计了一种具有自检测和自修复能力的结构。最后,以4×4乘法器为应用实例,通过仿真实验验证了细胞中存储器的自诊断、自修复能力和该仿生电路的自修复能力。
Embryonic Bio--inspired Circuit is a chip--level error--tolerant digital circuit whose design philosophy is inspired by multi-- cellular organism's grow process. This circuit consists of the two dimensional electronic cellular arrays. In this pape the theory, structure and fault--tolerant mechanism of this biologically inspired circuit are described. The discussion is also focused on the design of the compo- nents inside the cellular circuit and a circuit based on Hamming code with self--repairing memory in each cell. A 4 *4 multiplication circuit is presented to illustrate the benefits and features of this specially--designed circuit. The functionality and self--repairing capability of the memory are verified by the simulation results.
