Retrieve Data from DRAM

Retrieves data you request with Request Data from DRAM.

Inputs/Outputs

datatype_icon

reference in

Reference to a DRAM memory item.

datatype_icon

ready for output

Boolean value that specifies whether downstream nodes are ready for this node to return a new value.

Use Feedback Node to wire this input to the ready for input input of a downstream node. If this input is False during a given cycle, output valid returns False during that cycle.

True The downstream node is ready for the next data element.
False The downstream node is not ready for the next data element.

Default value: False

datatype_icon

reference out

Reference to a DRAM memory item.

datatype_icon

data

The data this node retrieves from the DRAM memory on the FPGA target.

datatype_icon

output valid

Boolean value that indicates whether this node computes a result that downstream nodes can use.

Wire this output to the input valid input of a downstream node to transfer data from the node to the downstream node.

True Downstream nodes can use the result this node computes.
False This node returns an undefined value that downstream nodes cannot use.
Note This node may return different undefined values when executed in simulation mode versus when executed on hardware.
