Abstract
A software GPS processing arrangement comprising a FIFO buffer for receiving a stream of the GPS signal samples, a memory, a DMA controller for transferring the GPS signal samples from the FIFO buffer to the memory, a CPU running GPS signal processing software configured to retrieve the GPS signal samples from the memory and process them to obtain a position fix, and a counter operating independently of the DMA controller and the CPU for keeping count of the number of streamed GPS signal samples.
