| Fix In Release: | C7000_3.1.0.LTS |
| Affected Platform/Device: | default |
| Workaround: | A potential workaround is to ensure that the streaming engine (SE) is set up to load more than 64-bits from the SE in a single access. |
| Description |
|
When (1) the streaming engine (SE) is being actively used by the programmer, and (2) when the streaming engine (SE) is set up to access 64-bits or less, and (3) when the result of the SE load is used in a scalar (non-vector) operation, the compiler may generate an illegal instruction that causes the assembly to emit a fatal error message. "test.asm", ERROR! at line 209: [E0003] Invalid instruction A potential workaround is to ensure that the SE is set up to load more than 64-bits from the SE in a single access. |
