I don't maintain a permanent blog, it would be great if this can be added in the FOSSi blog (if it qualifies).

For compute 32 bit is common when very high energy efficiency and density are required. Since GPGPUs often requires 4GB+ of memory, we need 64 bit addresses to access DRAM. This summer I worked under the vision of Prof. Taylor to initiate the support for custom intructions specifically designed for RISC-V based GP-GPU. We successfully supported 64 bit pointers using custom load and store instructions in address space 1 inside the RISC-V LLVM backend.
