4.4 Dynamic Overlay

OptiFlash FLC DMA engine can also be used to implement the overlay algorithm, to transfer critical code from on chip memory and Flash to TCM on demand basis. Along with ease of implementation, this can significantly improve the run-time program performance as overlay can happen in background without any CPU intervention.
