dc.description.abstract | This paper describes a Virtex-4 based system for aligning the code-phase of a received GPS signal. The core operation involves a multiplication of the received signal with a local replica of the code followed by integration of all possible alignments within the period of one code epoch. A speedup proportional to the code length is thus achieved. We outline the proposed system, which stores the code in on-chip memory blocks and uses both dedicated DSP hardware and user logic to perform MAC operations in parallel. We study area, time and energy usage as the ratio of user logic to custom blocks is varied and identify a design point and corresponding device size for which energy usage is minimized. | en_US |
