MIAOW (pronounced "me-ow") [Many-core Integrated Accelerator Of Waterdeep/Wisconsin] is an open source GPU created by the Vertical Research Group at the University of Wisconsin-Madison led by Professor Karu Sankaralingam. Based off of the publicly released Southern Islands ISA by AMD, MIAOW implements a compute unit suitable for performing architecture analysis and experimentation with GPGPU workloads. In addition to the Verilog HDL composing the compute unit, MIAOW also includes a suite of unit tests and benchmarks for regression testing.
A primary motivator for MIAOW's creation is the belief that software simulators of hardware such as CPUs and GPUs often miss many subtle aspects that can skew the performance, power, and other quantitative results that they produce. As an actual implementation of a GPU's logic, the Vertical Research Group believes that MIAOW can be a useful tool in producing not only more accurate quantitative results when benchmarking GPGPU workloads but also provide context for the architectural complexities of actually implementing newly proposed algorithms and designs that are intended to improve performance or other desired characteristics.
It must be emphasized that MIAOW represents a GPU's compute unit. It does not possess the auxiliary logic required to produce actual graphical output nor does it have logic to connect it to a specific memory interface or system bus. These extensions can be developed and we would welcome outside contributors for such efforts, but as MIAOW was created as a research tool their presence was not an absolute necessity in running benchmarks and experiments.
