Design, Implementation, and Verification of a Programmable Low-Cost Vertex Shader Based on Logarithmic Number System

This thesis focuses on efficient design of a vertex shader for per-vertex operations such as Transformation and Lighting in the OpenGL ES 2.0 graphics pipeline. The vertex shader performs these complex operations using logarithmic number system, and makes partial optimization for the hardware area based on the accuracy requirement of half-precision floating-point. The vertex shader design emphasizes low cost, and is well suited to low-accuracy embedded applications. The vertex shader is an SIMD (Single-Instruction-Multiple-Data) design with customized instruction set that allows users to write efficient vertex shader programs.
