In this paper, a new design for the accelerator of hand-held GPS base-band processing is proposed. This GPS accelerator has the following features: 12 parallel tracking channels and 128-bit parallel correlator for rapid acquisition and reacquisition; programmable Analog-to-Digital Converter (ADC) with inputting sample rate between 1.023 MHz and 16.368 MHz; channel status uploading through DMA; working clock frequency not less than 80MHz. With this new design, hand-held GPS receiver could achieve higher performance and lower power consumption.
