Overview

ADF graphs use data flow abstractions to read input data and write output data.

AIE API extends such abstractions to work with its aie::vector and aie::accum data types.

◆ aie::tlast

struct aie::tlast

template<typename T, typename Bool>
struct aie::tlast< T, Bool >

Type used to wrap objects read/written from/to streams that also encapsulates TLAST information.

When passed into output AXI streams, this object will say whether TLAST is asserted after the write operation. When read from input AXI streams, the object will say whether TLAST was asserted by the writer.
