Using the Nios II C2H Compiler

Figure 9–5. Mandelbrot Engine Pixel Interleaving

While the hardware accelerators are calculating a frame, the coordinates

of the next frame are prepared by the Nios II processor. The hardware

accelerator code contains a C pragma that instructs the compiler to

implement non-blocking accelerator which allows both the main

processor and Mandelbrot hardware accelerator to operate in parallel.

The main processor polls the accelerator to determine if the entire frame

has been rendered.
