发明名称 Memory reduction method for a DSP-based GPS processor
摘要 A method and apparatus for determining position in a GPS receiver (FIG. 4) is provided according to the invention. The apparatus includes a first switch (402), the first switch (402) receiving a digital GPS data, a first memory (409), a second memory (410) in parallel with the first memory, with the first memory and the second memory selectable by the first switch (402) for filling with the digital GPS data, and a second switch (416) selectable between the first memory (409) and the second memory (410) in order to extract the digital GPS data therefrom, wherein DSP signal processing (140) extracts digital GPS data from the first memory (409) while the second memory (410) is being filled and extracts digital GPS data from the second memory (410) while the first memory is being filled, and wherein the first memory (409) and the second memory (410) allow the digital GPS data to be processed in real time.
