Detailed Description

Block controller for a DMA FIFO block.

The DMA FIFO block has the following features:

One input- and output-port (type agnostic)
Configurable base address and FIFO depth
The base storage for the FIFO can be device specific. Usually it will be an off-chip SDRAM bank.

Member Function Documentation

◆ get_base_addr()

uint32_t uhd::rfnoc::dma_fifo_block_ctrl::get_base_addr ( const size_t chan ) const
