Abstract:
A GPS receiver comprising:correlation circuitry adapted to provide data corresponding to a correlation of a signal with a plurality of generated signals; control circuitry adapted to provide said plurality of generated signals to said correlation circuitry; circuitry adapted to receive and store said data from said correlation circuitry, said circuitry comprising: memory adapted to store said data from said correlation circuitry in a plurality of memory locations corresponding to a plurality of translated addresses; address translation logic adapted to provide said plurality of translated addresses each based on an address from memory access logic; and said memory access logic adapted to provide each said address to said address translation logic; and transform circuitry adapted to retrieve said data from said circuitry and transform said data into a frequency domain to produce transformed data, which is used by the GPS receiver to determine a frequency of said signal and a time offset associated with a ranging code carried in said signal.
