OCTSharp Software Architecture. On-board Ring Buffer: Default FIFO memory on the FG; DMA: Direct Memory Access; Frame Lost Event: a software event when the on-board ring buffer overflows; Frame buffer: A buffer for saving a raw B-Scan; Volume Buffer: A pre-allocated buffer for saving raw C-Scan; H2D: data transfer from the host frame buffer to the device memory in a GPU; D2H: data transfer from the device memory to a host page-locked memory; The flash signs represent a software trigger callback event.
