Abstract

This report is about the experiments of AMBA interface. In this report, the theories of AMBA protocol, AHB, APB, and AXI are described. The information of the experiments, which load images on a TFT-LCD with AXI-AHB module and load images with GPIO, is also included. The codes used at the experiments are explained on the end of this report with comments.

1. Objectives

Understanding AMBA interface and controlling a TFT-LCD with AXI-AHB module are the objectives of this experiment. To understand AMBA interface, three kinds of AMBA protocol are introduced. By understanding these protocols we can conduct the experiment successfully and we are able to learn well about AMBA interface by the experiment.

2. Theory

2.1. AMBA Protocol

AMBA protocol, Advanced Microcontroller Bus Architecture, is a protocol specifications defined by ARM company. AMBA is a standardizing protocol of on-chip bus which is usually used in the embedded system.
