# Documentation of Hummingbird E203 #

There will be three main docs to help user ramp up using the Hummingbird E203 Processor Core:

*    蜂鸟E203快速上手介绍.pdf
*    蜂鸟E203开源内核简介.pdf 
*    蜂鸟E203开源SoC简介.pdf

Besides, there are two more docs under different directories which is very useful:

*    https://github.com/SI-RISCV/e200_opensource/tree/master/boards/ 蜂鸟FPGA开发板和JTAG调试器介绍.pdf
*    https://github.com/SI-RISCV/hbird-e-sdk/tree/master/software/FreeRTOSv9.0.0/ 蜂鸟E203移植FreeRTOS.pdf

The Hummingbird E203 Core was deeply introduced in the published Book (蜂鸟E200处理器核在如下出版中文书籍中进行深入浅出的分析讲解):

Dedicated FPGA-Board and JTAG-Debugger 
-----------------------------
In order to easy user to study RISC-V in a quick and easy way, we have made a dedicated FPGA-Board and JTAG-Debugger.  Diagram as below:
