Expected behavior:

Observed behavior: Venus ran into a simulator error!

Attempting to access uninitialized memory between the stack and heap. Attempting to access '4' bytes at address '536871044'

Question: I tried using Venus but still need help figuring out where this happens. Thanks

Try using the online version. It should break at the instruction where this happens with a red marker.

And double-check how you're storing the result of the dot product. Remember that the result of the dot function is just a 4-byte value.

Check a6 and t4. Seems like your destination pointer could be wrong.

sw a0, 0(s3) is the instruction that crashes

s3 = a6 + t4 so either a6 is wrong or t4. It seems like t4 (its 0x1000003C) clearly a wrong offset
