Abstract
The rapid evolution of mobile computing between 2000 and 2018 has relied heavily on advances in Very Large Scale Integration (VLSI) technology which has enabled the miniaturization acceleration and energy optimization of complex digital systems. Among the most computationally intensive components within mobile system-on-chip (SoC) architectures are mobile 3D graphics processors that must execute geometric transformations shading computations raster operations and rendering tasks in real time while operating under strict power and thermal constraints. Traditional binary floating-point computation architectures face performance bottlenecks in division operations which often require expensive hardware long latency cycles and high energy consumption. In contrast the Logarithmic Number System (LNS) offers an innovative approach to performing arithmetic operations by converting multiplication and division into simple add/subtract operations in the logarithmic domain. Integrating an LNS divider into a VLSI-based 3D mobile graphics engine can greatly improve computational throughput reduce silicon area and enhance rendering efficiency.
