Using FIFOs in hardware-software co-design for FPGA based embedded systems

This paper deals with the evaluation of FIFO for connecting custom cores to processors in FPGA. Two case studies were done in order to evaluate the use of FIFO in the context of hardware-software co-design. One case study analyzes the rendering images of the Mandelbrot set and the other one deals with the game of Connect Four. In both applications a simple co-processor provides the most speed-up, where a higher quality co-processor implementation was exhibited.
