c - 请对Tasking Tricore Compiler显示的以下错误提出建议

我为Tricore控制器编写了一个C程序，在编译之后，我得到了下面的错误消息，实际上我无法理解你能给我一些建议吗？
我可以猜测它与内存层次结构有关，但仍然无法找出实际的问题。

最佳答案

我不知道Tricore控制器，但看起来你已经超出了一些限制我假设这个控制器的资源非常有限，并且生成过程检查您没有超过它们。
requirement: 193K (0x304c8) bytes of RAM area in space spe:tc:linear一定是说你用了193K的东西，太多了。
.bss.Pro2.group (60) (0x30140 bytes)意味着大部分来自BSS部分（即静态未初始化变量）。
我没有计算，但是points group[181][M * N / 2];的大小可能是主要问题。
