APB protocol. Using this book This specification is organized into the following chapters: Chapter 1 Introduction Read this for an overview of the APB protocol. Chapter 2 Signal Descriptions Read this for a description of the APB signals and their characteristics. Chapter 3 Transfers

For designing AMBA APB protocol for read and write operation, we are using Moore finite state machine(FSM). To design FSM, we need a way to express the FSM in Verilog: 1. A state encoding for each state. -- create state encoding with Verilog parameters. 2. A mechanism for keeping track of the current state.

Flow control，APB的上级模块，需要给到流控信号，告知APB master什么时候开始传输，什么时候结束。 FSM，必须完全遵循AMBA的datasheet。 时序对齐，和FSM一样，接口时序要和APB协议对齐。

This paper gives an outline of the AMBA bus architecture and explain the APB bus in detail. The APB bus is designed using the Verilog HDL according to the specification and is verified using EDAplaground. The simulation results show that the data read from a particular memory location is same as the data written to the given memory location.

APB is low bandwidth and low performance bus. So, the components requiring lower bandwidth like the peripheral devices such as UART, Keypad, Timer and PIO (Peripheral Input Output) devices are connected to the APB. The bridge connects the high performance AHB or …

To achieve high performance proposed architecture is FSM based pipelined APB-to-AHP Bridge and Vice-versa. This also involves the Back notation for Synthesized of Bridge module and to perform Functional and Timing Simulation using Xilinx ISE.

APB (advanced peripheral bus) is non-pipelined, used for connection with low bandwidth peripheral which does not require the AXI (high performance) protocol. To simply the integration of APB peripherals into a design flow it relates a signal transition to the rising edge of the clock.
