Set Instruction FIFO Depth (G Dataflow)

Last Modified: September 9, 2016

Sets the depth, in elements, of the host memory part of the Host to Target DMA FIFO used to transfer instructions from a host node to a corresponding FPGA node.

When Open Session is called, it sets the depth of the instruction FIFO to a reasonable value and stores that value within the session. When this node is called, the FIFO is configured to the new instruction fifo depth and this value is stored in the session. Use this node only in applications where the default setting is not sufficient.

instruction fifo depth

Specifies the depth, in elements, of the host memory part of the Host to Target DMA FIFO used to transfer instructions from this host node to the corresponding FPGA node.
