8168增加tiler内存的问题



tiler内存紧张 希望把tiler从256M放大一些

 

做了下面修改 发现编码马赛克严重 花屏

 

1  tiler.cfg

Program.global.XDC_CFG_TILER_MEM_8BIT_SIZE  =  192 *MB;

Program.global.XDC_CFG_TILER_MEM_16BIT_SIZE =  (tilerMemSection.len - 192* MB);

 

2 config_2G.bld

var TILER_SIZE                  = 384 * MB;
var SR3_FRAME_BUFFER_EXTRA_SIZE     = 128 * MB;

 

  • 你好,

    请参考DMM相关介绍tiler的章节。里面提到每个mode container的大小为128MB。在我们的软件里面我们使用到了8-bit mode container (for Y),16-bit mode container ( for UV)。最大只能是128MB+128MB=256MB。不能扩大。这是硬件限制。
