Scalar And Control Reference¶
This tree documents the pto.* scalar and control instructions of PTO ISA: synchronization, DMA configuration, predicate-state movement, predicate construction, and the shared scalar source shell around tile and vector payload execution.
The key distinction is architectural role, not only spelling. pto.* pages live here when they expose control, DMA, predicate, or other non-payload state directly. When an instruction set exists only to summarize how those forms interact with vector execution, the vector instruction-set overviews remain linked as related material rather than acting as the primary per-op reference.
