LLVM RISC-V RV32X Graphics Extension Support and Characteristics Analysis of Graphics Programs

In recent years, virtual reality technology has become the dominant means of human-computer interaction, with computer graphics rendering being a crucial component in realizing experiences. Rendering is an interdisciplinary field that encompasses various disciplines, including science, mathematics, and physics. Consequently, it faces challenges when comes to designing processors extension instruction sets based on RISC-V architecture. This paper utilizes LLVM compiler design support for RV32X instructions, encompassing both assembly-level compilation-level support. It compiles program conjunction compilation tool chain. Feature extraction performed using script feature analysis tools. The microarchitecture-independent characteristics programs architecture, X86 ARM architecture are compared analyzed at level memory level. experimental results demonstrate ray tracing test exhibits higher instruction-level parallelism program, but lower than program. Moreover, terms mix, proportion arithmetic instructions access while Additionally, relatively short reuse distance, enabling efficient data registers reducing need frequent access.
