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 itsaie::vectorandaie::accumdata types.

window_readincr_v()[2/2]

templateaie_dm_resourceResource = 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.

Parameters
