Abstract
Arithmetic Logic Units (ALUs) are key elements within processors, executing a variety of operations including multiplication, division, addition, and subtraction. Among these, multiplication stands out as the most frequently utilized function within ALUs. This study presents an innovative MSI-interfaced multiplier architecture designed for integration into a multi-precision floating-point multiplier framework. This novel architecture offers configurations for 24-bit, 53-bit, 113-bit, and 237-bit binary operations, corresponding to single, double, quadruple, and octuple precision modes of floating-point computation. Notably, it enhances throughput by accommodating the multiplication of multiple batches of inputs with each operation initiation, surpassing existing binary multiplication systems. A unique Mantissa Similarity Investigation (MSI) implementation is developed and integrated into the binary multiplier architecture. Comparative analysis of the path delay in 24-bit mode against existing 24-bit multipliers demonstrates that the novel MSI-interfaced binary multiplier architecture, with and without MSI, exhibits reduced path delay compared to all existing systems, as anticipated.
