User Space Components - UG1433

The Linux user space components used are:

• The rftool is the Linux application that receives commands over the Ethernet from the PC GUI and performs appropriate actions.
• RFDC user space drivers provide APIs for communication with the RFDC hardware.
• RFCLK user space drivers provide APIs for communications with external CLK104 daughter boards.
  Note: See Software Design Notes — Multimaster Access of CLK104 on TCA9548 Multiplexer.
• DMA client driver interface /dev/pl_mem is used to allocate a buffer from the PL DDR, and is also used to trigger a DMA transaction from the user space.
