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. XUPV2P development board

II.XUPV2P development board

II.XUPV2P development board

III.FPGA Features FPGA 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 Systems An 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 Features Reliability 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 System Linux 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).

VII. Petalinux Cross-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.

VIII. Petalinux Setup Step

IX. Xilinx Platform Studio(XPS) Select the OS

Select device

Generate file auto-config.in

X. Building and Dowloading a Linux Set Environment Variables

Installation GNU Compiler Collection(GCC).

uClinux Source packages www.uclinux.org/pub/uClinux/dist/

make menuconfig EDK file import and uClinux basic configuration. Then autoconfig.in copy to Linux . (/linux- 2.4.x/arch/microblaze/platform/uclinux-auto) make menuconfig

Select CPU

Select driver

Generate file image.bin

Dowloading

XI. Conclusion Products come more quickly Higher flexibility Renewable and design reuse Long product life cycle 資料來源：Gartner(2010) 1999～2014年FPGA中處理器的發展
