Based on an efficient algorithm of Euclidean distance transform for binary images, a circuit of O (N^2) size is proposed. With in-place calculation, both the intermediate data storing and the result output use the same menmory with the input data. This reduces the amount of menmory largely. By replacing multipliers with coumters, comparators, and adders, the circuit size is further reduced and its calculation speed is improved also. 相似文献

A set of integrated Orthogonal Frequency Division Multiplexing (OFDM) modulation and demodulation system is proposed and its performance is verified in reference to the standard of IEEE802.16a for WMAN. The design, combined with analogy front-end, adopts Texas Instrument ( TI ) Company's 6701 evaluation module (EVM) to construct digital Intermediate Frequency (IF) platform. A DSP-based baseband processing software module is embedded into the system. The proposed scheme makes it possible for users to select various software modules to set up corrections with different throughput performance. Taking into account the given hardware configuration, the design aims to optimize the algorithm modules to accomplish better system performance. 相似文献
