SPT3.1 maxs.gm Compilation Error？

Shi_test · ‎03-13-2023

my s32r45 board:

The first pic is my SPT3.1.

The second pic is Compilation result.

VEC_SZ=0x2000 is the OPRAM max,but it con't work!

If VEC_SZ=0x1FFF,the Compile successfully.

Is this a bug?

Hello,

For the max spt instruction, the maximal vector size is 0x2000(8192), but the field is only 13 bit, maximal number is 0x1FFF, but Vector length Must be a multiple of 8, so the least 3-bit is ignored.and VEC_SZ = 0 implies vector length = 8192. please check the reference manual.

Best regards,

Peter
