Adaptive Low-Error Fixed-Width Booth Multipliers
In this paper, we propose two 2’s-complement fixed-width Booth multipliers that can generate an n-bit product from an n-bit multiplicand and an n-bit multiplier. Compared with previous designs, our multipliers have smaller truncation error, less area, and smaller time delay in the critical paths. A four-step approach is adopted to search for the best errorcompensation bias in designing a multip...
متن کاملFixed Width Booth Multiplier using Error Compensation
In many multimedia and digital-signal processing (DSP) applications, multipliers are considered to be the basic arithmetic units. These multipliers significantly influence the system’s performance and power dissipation. To achieve high performance, the modified Booth encoding has been widely adopted in parallel multipliers. It reduces the number of partial products through performing multiplier...
متن کاملError Compensated Fixed Width Modified Booth Multiplier for Multimedia Applications
Many multimedia and digital signal processing systems are desirable to maintain a fixed format and to allow little accuracy loss to output data. The objective of this paper is to design a fixed width modified booth multiplier with high error performance. And the need to derive an effective error compensation function that makes the error distribution more symmetric and centralized in the error ...
متن کاملHigh Accuracy Fixed-width Booth Multipliers with Probabilistic Estimation Compensated Method
In this research, a probabilistic estimation compensation (PEC) method for fixed-width Booth multiplier is proposed. According to the probabilistic analysis for the truncation part,a formula is obtained to calculate the compensation value easily. In the application of long bit width, the PEC method is implemented by a simple compensation circuit without the exhaustive simulation to achieve a hi...
