Re: 关于 ULP 的 SUB 指令产生 ALU overflow 的问题
减法运算中,正数减负数也可能产生溢出,正溢出; 同理,负数减正数产生的溢出为负溢出
当进行加(减)法计算的时候,进(借)位是常见的现象。当出现了补码后,溢出,也是常见的.

Is it possible to use structs in the ULP coprocessor
There is I found .struct expression
https://sourceware.org/binutils/docs/as/Struct.html
.struct 0
field1:
.struct field1 + 4
field2:
.struct field2 + 4
field3:
So in ESP32 compatible with this feature? Could I see an example here?
