蓝牙HCI-UART主控制接口的FPGA设计与实现

The Design and Implemation of Bluetooth HCI-UART Host Control Interface Based on FPGA

蓝牙技术作为一种短距离的无线通信技术,具有巨大的发展潜力,本文意从HCI层进行蓝牙技术的应用开发。本文首先介绍了HCI和UART的结构与原理,在分析和比较HCI三种类型接口USB、RS-232和UART优缺点的基础,提出了一种基于FPGA采用硬件设计HCI-UART的实现方式。本设计在QuartusII9.0集成设计环境下,采用硬件描述语言Verilog分模块设计完成,设计经过Modelsim6.4a仿真与验证。

Bluetooth, as a short-range wireless communications technology, has a tremendous development potential. This article tries on the application development of Bluetooth based on the HCI layer. At first, this paper introduces the structure and principle of HCI and UART of HCI. On the basis of the analysis and comparison of the advantages and disadvantages of the three types of interfaces USB, RS-232 and UART, a methond using hardware to design HCI-UART based on FPGA is given in the paper. The design is completed in the integrated design environment of Quartus Ⅱ 9.0 and diveded into seveeral modules which is completed by use of hardware description language Verilog. The design is simulated and verified by Modelsim 6.4a.
