| 英文摘要: |
| To solve the excessive huge scale problem of the traditional multi-bit digital artificial neural networks (ANN) hardware implementation methods, a bit-stream ANN construction method based on direct sigma-delta (Σ-Δ) signal processing is presented. The bit-stream adder, multiplier and fully digital Σ-Δmodulator used in the bit-stream linear ANN are implemented in a field programmable gate array (FPGA). A bit-stream linear ANN based on these bit-stream modules is presented and implemented. To verify the function and performance of the bit-stream linear ANN, the bit-stream adaptive predictor and the bit-stream adaptive noise cancellation system are presented. The predicted result of the bit-stream adaptive predictor is very close to the desired signal. Also, the bit-stream adaptive noise cancellation system removes the electric power noise effectively. |
