The document discusses instruction set architecture (ISA) customization. It proposes grouping dataflow independent operations in application software as potential new complex instructions. These new instructions would form an extended instruction set used for code generation and execution. It also proposes customizing a basic processor by extending it with units specialized for each particular application, resulting in differently customized processor versions tailored for different products. The document is authored by Andrea Tommaso Bonanno, Valerio Panzica La Manna, and Alfredo Motta for Prof. Donatella Sciuto concerning an HPPS project on June 19, 2008.
