      @范老师，能否提供和RTL匹配的C或C++作为研究（而且仿真的时候是要和golden数据对比的），谢谢~

        Is this IP based on SW? or pure HW?
        How about the max compressing rate is? and the lowest latency?

            @brucezhan Not FPGA, If you use 65nm, it can reach 400MHz

                  @yx9527 后面出个参考软件给大家，自己跑吧 😃
                  说实话，目前曲线上结果不是太好，别期望太高哦。正在进一步改进中

                    @bo 范老师，C Model大概什么时候发布？会发布源代码吗？

                      @fighting C Model暂时不开放源代码，会对参与项目开发的人员开放代码。一般用户其实只需要RTL就够了

                        范老师，您好！ 我一部分工作是作视频处理算法的，从事IC设计有十余载，希望有机会可以参与贵团队的工作，无论编码、设计、架构、优化都可以。 真的非常高兴国内有越来越多这样的共创平台。

                              范老师, 如果真想拿个asic SoC 项目把这个VENC 集成进去
                              －－这其实也是件很快的事情，因为我本来就有这样的SoC项目，用的是verisillicon的h.265；
                              跑一跑SoC的top仿真，
                              以及放到emulator上也就是用FPGA搭建的emulation的环境上跑跑的话，
                              还是需要更多测试例的，如果能开放相应的C model就好了，
                              我可以将C model 修改得更接近UVM平台 得架构， 对关键模块及节点进行自动化实时数据对比。
                              我真的非常急切渴望知道和确定RTL代码的实际可用性！

                                    @bo ，can you share cmodel or x265,which we can compare your encoder performance with others!

                                          范教授您好，我是一名视频编解码的学习者，想问下您能否提供一份这个Encoder IP CORE的说明文档呢？
