      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, 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!
