Lut was replaced by the method taking triangle wave and differential in the line phase locked circuit , so it saves the hardware area and cost 在行鎖相中,用取三角波然后差分的方法替換了查找表,減小了芯片面積,降低了成本。
In addition , both the series - parallel connection and parallel pipeline for the circuit structure are availed to cut down hardware area and improve processing speed of the system 同時,為保證系統(tǒng)的實時處理速度和降低硬件成本,在算法的vlsi實現(xiàn)時采用串并結合和并行流水線等設計。
