The AHB2APB interfaces the AHB to the APB. It buffers address, control and data from the AHB, drives the APB peripherals and returns data and response signals to the AHB. It decodes the address using an internal address map to select the peripheral.
详细74hc595芯片资料The ’HC595 devices contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage regis

一. 简介
《Time, Clocks, and the Ordering of Events in a Distributed System》是大神Leslie Lamport写的一篇关于时钟序列的文章。本文影响极其深远，可以说是分布式领域开山奠基式的重要文章。而该作者Leslie Lamport，同时也是共识算法Paxos的发明者，也是Latex的创作者，是一位非常可敬的牛人。
此文不长，主要以提出算法和数学证明为主。在这里我主要记录算法的主要思想，具体证明过程请参考原文深入了解。
