我为 Tricore 控制器编写了一个 C 程序，编译后我收到以下错误消息，我实际上无法弄清楚。你能提供一些意见吗？

我可以猜测它与内存层次结构有关，但仍然无法找出实际问题。

I don't know the Tricore controller, but this looks like you've exceeded some limit. I assume this controller has very limited resources, and the build process checks that you didn't exceed them.

requirement: 193K (0x304c8) bytes of RAM area in space spe:tc:linear must mean you used 193K of something, which is too much.
.bss.Pro2.group (60) (0x30140 bytes) means most of this comes from a BSS section (i.e. static uninitialized variables).

I didn't do the math, but the size of points group[181][M * N / 2]; is probably the main issue.
