模拟可编程阵列处理器（APAP）的生物启发模型，基于对脊椎动物视网膜的研究，允许在VLSI中实现复杂的可编程时空动态。该模型模拟了图像在视觉通路中的处理方式，为在标准技术中实施早期视觉任务提供了可行的替代方案。在0.5 /spl μ/mCMOS上设计并制作了一个原型芯片。它提供了每硅面积的计算能力和功耗，是单芯片报告的最高功耗之一。本文详细介绍了生物启发网络模型、模拟构建模块设计挑战和权衡以及一些功能测试结果。
A bio-inspired model for an analog programmable array processor (APAP), based on studies on the vertebrate retina, has permitted the realization of complex programmable spatio-temporal dynamics in VLSI. This model mimics the way in which images are processed in the visual pathway, what renders a feasible alternative for the implementation of early vision tasks in standard technologies. A prototype chip has been designed and fabricated in 0.5 /spl mu/m CMOS. It renders a computing power per silicon area and power consumption that is amongst the highest reported for a single chip. The details of the bio-inspired network model, the analog building block design challenges and trade-offs and some functional tests results are presented in this paper.
