标题: TL138 ad7606_dsp共享内存的问题
我用使用TL138的ad7606_dsp demo程序 发现运行在128k采样速率时 随着运行时间的变化ipc_ring_buffer出现问题了 剩余的内存最后为0了 也就是没有release掉 不知道各位之前注意到这个问题没有 是否有好的解决方法？求赐教~# [9 A4 f- i* c8 L7 B0 w" p; B

一两分钟的样子，您也可以试一下~

128k 的时候 arm 端画图时处理负荷过大，会造成用于缓存数据的内存不断增多，不能及时进行release，是会出现那样的情况的

" P2 a4 d. i# _3 x: x+ n您的意思是这个问题是ARM引起来的？我一直以为是DSP那端的问题~~ 有什么好的解决方法吗？或者您帮我指个方向  哈哈~~~

ARM 端波形绘制部分还有较大优化空间
