MIAOW - An open source RTL implementation of a GPGPU

Graphic Processing Unit (GPU) based general purpose computing is developing as a viable alternative to CPU based computing in many domains. In this paper, we introduce MIAOW (Many-core Integrated Accelerator Of Wisconsin), an open source RTL implementation of the AMD Southern Islands GPGPU ISA, capable of running unmodified OpenCL-based applications. We present our design motivated by our goals to create a realistic, flexible, OpenCL compatible GPGPU, capable of emulating a full system. We demonstrate that MIAOW enables disruptive and transformative research and has the potential to bring all of the benefits of open source development to GPUs in real products in the long term.
