提出了一种基于时钟相位抖动的混沌随机数产生器,并在XilinxFPGA开发板上实现并进行了测试。测试结果表明,最高输出速率达8Mbps,实现了设计要求。硬件结构简单,并且该RNG的输入源不受电路噪声源的影响,易于今后的IC实现。

This paper presents the Top-Down methodology design of the AMBA 2.0 architecture which is comprised of AHB and APB. The paper describes all components by RTL models and focuses on the key modules: the arbiter and the AHB/APB bridge. The architecture has been implemented on FPGA at a frequency of 53.6MHz. The RTL model of the architecture has also been synthesized using 0.18μm library and its highest frequency could get 150MHz.
