I. INTRODUCTION This paper describes a embedded systems on field-

programmable gate array(FPGA) .

The paper focuses on Linux operating system for Xilinx’s MicroBlaze based embedded platforms.

III.FPGA FeaturesFPGA compatible with the PLD

(Programmable Logic Device)and the advantages of universal gate array(NAND and NOR) can achieve large-scale circuitry.

Programming is also very flexible.

It also has a short development cycle design, advanced development tools, standard products without testing, stable quality and a real-time online testing.

IV. Embedded SystemsAn embedded system can be defined as a

special purpose computer .

Many of these systems are focused on performing a multiplex task, or a very limited set of tasks.

Sometimes need to meet some restrictions such as real-time operation, cost, size or power consumption constraints.

V. Embedded System FeaturesReliability and security

The system must be reliable and secure against errors.

Interaction with physical devices The communication of embedded systems is

performed through unusual input/output devices that sometimes require signal conditioning.

Robustness The conditions of the embedded systems operation

may be adverse, so they must be as robust as possible. For example these systems may be placed inside a vehicle with different operating conditions.

VI. Embedded Linux SystemLinux kernel has granularity and

modularity that make it easy to configure it to work on the hardware.

An embedded system may need a flash file system (CRAMFS or JFFS2).

10

VII. PetalinuxCross-compiler tool chain 、 Linux

kernel 、 GNU software 、 debugger and C/C++ libraries.

PetaLinux incorporates all these features in the development environment that integrates with EDK and ISE Xilinx tools, and through AutoConfig tool simplifies synchronization between hardware and software.
