download()

UHD_API void uhd::rfnoc::dram::download	(	rfnoc_graph::sptr	graph,
		const void *	buff,
		const size_t	nsamps,
		const std::string &	cpu_fmt,
		const std::string &	otw_fmt = "sc16",
		replay_block_control::sptr	replay = nullptr,
		size_t	port = 0,
		size_t	offset = 0
	)

Receives data from an RFNoC replay block

This receives samples from an RFNoC replay block. It handles common data losses that can occur when receiving data over a network interface using UDP. If a block is connected to the input port of the replay block it will be temporarily disconnected and reconnected after transfer.

Parameters

graph	RFNoc graph to operate on
buff	buffer to received data into
nsamps	number of samples in buff
cpu_fmt	format of the data in buff, must match the data in buff
otw_fmt	format of the data over the wire, there must be a matching converter between cpu_fmt and otw_fmt (default: "sc16")
replay	Replay block to send the data to (default: nullptr, will use the first available)
port	output port to be used on the replay block (default: 0)
offset	offset in the replay where to read the data (default: 0)

upload()

UHD_API void uhd::rfnoc::dram::upload	(	rfnoc_graph::sptr	graph,
		const void *	buff,
		const size_t	nsamps,
		const std::string &	cpu_fmt,
		const std::string &	otw_fmt = "sc16",
		replay_block_control::sptr	replay = nullptr,
		size_t	port = 0,
		size_t	offset = 0
	)

Send samples to a RFNoC replay block.

This sends samples to a RFNoC replay block. It handles common data losses that can occur when sending data over a network interface using UDP. The stream buffer has to be a one dimensional array. If a block is connected to the input port of the replay block it will be temporarily disconnected and reconnected after transfer.

Parameters

graph	RFNoC graph to operate on
buff	buffer to be sent
nsamps	number of samples in buff
cpu_fmt	format of the data in buff, must match the data in buff
otw_fmt	format of the data over the wire, there must be a matching converter between cpu_fmt and otw_fmt (default: "sc16")
replay	Replay block to send the data to (default: nullptr, will use the first available)
port	input port to be used on the replay block (default: 0)
offset	offset in the replay where to store the data (default: 0)
