| 针对多路有限长单脉冲响应(Finite Impulse Response, FIR)滤波器实现结构的资源需求量有待降低的问题，本文根据多路采样数据的时分多路复用传输机制，通过使多路采样数据复用同一单路FIR滤波器，对多路FIR滤波器的FPGA实现结构进行优化。分析证明，该优化实现结构由不同类型的单路FIR滤波器实现结构构成时，与典型多路FIR滤波器实现结构相比，其寄存器需求量大幅降低，同时可以保证乘法器和加法器需求量大幅降低或大致相同。 |
| 英文摘要: |
| Because the demand for resources of multi-channel Finite Impulse Response (FIR) filter implementation structure is to be reduced, the paper optimizes the implementation structure of multi-channel FIR filter whose multi-channel input data are transported through time-division multiplexed mechanism. In the optimized structure of FIR filter which is implemented in FPGA the multi-channel input data share the same single-channel FIR filter. Compared to the typical structure of multi-channel FIR filter, the resource evaluation proves that when the optimized structure is formed by different kinds of single-channel FIR filters, it achieves significant reduction in the demand of registers, and it is roughly the same or achieves significant reduction in the demands of multipliers and adders. |
