10 Alliance application or protocol level specifications. This includes the physical interface, electrical interface, 11 low-level timing and the PHY-level protocol. The goal has been to define a C-PHY high-speed interface that 12 can coexist on the same pins as the MIPI D-PHY interface. These functional areas taken together are known 13 as C-PHY.

1 This specification provides a flexible, low-cost, High-Speed serial interface solution for communication 2 interconnection between components inside a mobile device. Traditionally, these interfaces are CMOS 3 parallel busses at low bit rates with slow edges for EMI reasons. The D-PHY solution enables significant 4 extension of the interface bandwidth for more advanced applications. The D-PHY solution can be realized 5 with very low power consumption.

AMBA AHB-Lite 是面向高性能的可综合设计，提供了一个总线接口来支持 Master 并提供高操作带宽。 AHB-Lite是为高性能，高频率系统设计的，特性包括： • Burst传输 • 单边操作 • 非三态 • 宽数据位，包括64、128、256、512和1024位 最普通的 AHB-Lite 从器件是内存器件，外部存储器接口和高带宽外围器件。 虽然低带宽外围器件可以连接到 AHB-Lite，但从系统性能考虑，应 当连接 到 APB 总线上，可以通过 APB 桥接实现。 图 1-1 是一个具有一个 Master 的 AHB-Lite 的系统，包括一个 Master 和三 个 Slave。利用内部逻辑生成了一个地址解码器和一个 Slave-to-Master 多路 转换器。
