This study developed a high accuracy dynamic error-compensation circuit for fixed-width Booth multipliers based on probability and computer simulation (PACS). PACS begins by generating several potential solutions based on both conditional and expected probability, whereupon the accuracy of the solutions is verified using computer simulation and the solution with the highest accuracy is selected. In addition to being highly accurate, the proposed PACS approach is area-effective. This study used the TSMC 0.18-μm CMOS to fabricate a 16-bit Booth multiplier with an operating frequency of 100 MHz and power consumption of 6.7 mW.
