Methods, devices, and systems for automatically determining how an application program may be partitioned and offloaded for execution by a general purpose applications processor and an auxiliary processor (e.g., a DSP, GPU, etc.) within a mobile device. The mobile device may determine the portions of the application code that are best suited for execution on the auxiliary processor based on pattern-matching of directed acyclic graphs (DAGS). In particular, the mobile device may identify one or more patterns in the code, particularly in a data flow graph of the code, comparing each identified code pattern to predefined graph patterns known to have a certain benefit when executed on the auxiliary processor (e.g., a DSP). The mobile device may determine the costs and/or benefits of executing the portions of code on the auxiliary processor, and may offload portions that have low costs and/or high benefits related to the auxiliary processor.
