Abstract
The paper presents a model for simultaneous instruction selection, compaction, and register allocation. An arc mapping model, along with logical propositions is used to create an optimization model. Code is generated in fast cpu times and is optimized for minimum code size, maximum performance or estimated energy dissipation. Code generated for realistic DSP applications provides performance and code size improvements from 1.09 up to 2.18 times for the TMS320C2x processor compared to previous research and a commercial compiler. In all examples, up to 106 instructions are generated in under one cpu minute. This research is important for industry since DSP code can be efficiently generated with constraints on code size, performance and energy dissipation.
