General Restrictions

For user-defined tensors, the start address of the allocated buffer scope will be aligned according to Table 1.

To call the TIK APIs for data compute and transfer, the destination and source operands must meet the address offset alignment restrictions specified in Table 1. The restrictions specified by each TIK API apply in the case of restriction inconsistency.

**Table 1** Alignment restrictions for different scopes
Scope	Alignment Requirement
Unified Buffer	Atlas training product: 32-byte aligned Atlas inference product AI Core: 32-byte aligned Atlas inference product Vector Core: 32-byte aligned Atlas A2 training product/Atlas A2 inference product: 32-byte aligned Atlas 200I/500 A2 inference product: 32-byte aligned
L1 Buffer	512-byte aligned
L1OUT Buffer	512-byte aligned for float16; 1024-byte aligned for float32, int32, and uint32
Global Memory	No alignment requirement
