基于FPGA和uClinux的显示系统

介绍了一种以FPGA为硬件核心,uClinux为软件基础的具有独显,多图层,多任务等特点的显示系统。本文详细的论述了该系统硬件结构及软件设计流程,首先设计了显示IP核,接着进行uClinux驱动程序开发,最后移植microwin来管理图形显示。本显示系统具有很好的可移植性,稍作改动便可应用于不同类型应用场合。

Based on FPGA and uClinux display system

Introduced a display system which choose FPGA chip as the system hardware,use uClinux as the system software,the system has some characters such as Separate-memory,multi-layer display channals,multitask.we present the system hardware structure and software design flow.At first,we design diplay IP core,then we design the uClinux driver and transport the microwin which used to manager the user interface.This display system has the very good probability,and can be possible to apply in the different type application situation after modificated.
