Abstract
Integer division is a fundamental operation in computer arithmetic, widely used in applications such as digital signal processing, cryptography, and artificial intelligence. However, due to its inherently sequential nature, integer division often becomes a performance bottleneck in modern computing systems. This paper presents a novel variable latency integer division algorithm, implemented and synthesized in 15nm technology using Cadence software. The proposed design dynamically skips unnecessary iterations by exploiting the relationship between the number of leading zeros in the divisor and the partial remainder, significantly reducing average latency and power consumption. Our implementation achieves an average latency of 1.45 clock cycles per 32-bit division, outperforming existing state-of-the-art designs. The design is validated through extensive simulations and benchmark testing, demonstrating its suitability for low-power embedded systems and high-performance computing applications.
