Interoperability with Adaptive Data Flow (ADF) Graph Abstractions

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.

Constructor & Destructor Documentation

tlast()

template<typename T , typename Bool >

constexpr aie::tlast< T, Bool >::tlast ( T  value, Bool  t_last  )

inlineconstexpr

Constructor used to initialize the object. For input AXI streams, both arguments are references to the variables where to store the read value and TLAST. For output AXI streams, these are the value and TLAST to be written.

aie::TLast

interface aie::TLast

Concept for tlast objects passed to << and >> operators with streams.

template<unsigned N, aie_dm_resource Resource = aie_dm_resource::none, typename T = void>

void window_readincr_v	(	input_window< T > *	w,
		aie::vector< T, N > &	value
	)

Read a vector from an input window and increment the window pointer.

window_write()

template<aie_dm_resource Resource = aie_dm_resource::none, unsigned N = 0, typename T = void>

void window_write	(	output_window< T > *	w,
		const aie::vector< T, N > &	value
	)

Write a vector into an output window.

Parameters

w	Output window
value	Vector to be written

window_writeincr()

template<aie_dm_resource Resource = aie_dm_resource::none, unsigned N = 0, typename T = void>

void window_writeincr	(	output_window< T > *	w,
		const aie::vector< T, N > &	value

writeincr() [1/3]

template<aie::AccumElemBaseType T, unsigned N>

void writeincr	(	output_stream< T > *	w,
		const aie::accum< T, N > &	value

value	Accumulator to be written

writeincr() [2/3]

template<aie_stream_resource_out Resource = aie_stream_resource_out::none, typename T , unsigned N>

void writeincr	(	output_stream< T > *	w,
		const aie::vector< T, N > &	value
	)

Writes a vector into the output AXI stream. TLAST is not asserted.

Template Parameters

Resource

Stream out resource. This information can be leveraged by the compiler to schedule stream writes in parallel when possible

Parameters

w	Output stream
value	Vector to be written

writeincr() [3/3]

template<aie_stream_resource_out Resource = aie_stream_resource_out::none, typename T , unsigned N>

void writeincr	(	output_stream< T > *	w,
		const aie::vector< T, N > &	value,
		bool	tlast
	)

Writes a vector into the output AXI stream. An additional argument says whether TLAST is asserted.

Template Parameters

Resource

Stream out resource. This information can be leveraged by the compiler to schedule stream writes in parallel when possible

Parameters

w	Output stream
value	Vector to be written
tlast	TLAST is asserted if true
