Runtime Driver

This repo contains AWS-FPGA compatible Runtime C Drivers that will drive the AWS-FPGA CL Designs to interract with the Cloud FPGA via AFI.

How to Run

  1. First Copy the Driver you want to run. (Considering the AFI is loaded in slot 0)
  2. Paste it in your design's software/runtime directory.
  3. Open Terminal in this directory.
  4. First type make driverName (for example if the driver is loader.c then type make loader)
  5. Then once the driver is compiled successfully type sudo ./driverName (for example if driver if bramLoader.c then type sudo ./loader *args)
  6. All the interactions that the driver has done with the FPGA will be shown on the terminal screen

Drivers

This repo contains the following drivers

Driver Format Purpose
Loader ./loader <hex-file>/<elf-file> dma/bram Reads a hex/elf file and stores the data into BRAM/DMA (WORD aligned)
UART ./uart_runtime Transmit and Receive data through UART via OCL Interface
