Triggered Ar hite tures

Embedded omputer systems an be found everywhere as the result of the need to develop ever more intelligent and omplex ele troni devi es. To meet require-ments for fa tors su h as power onsumpiton and performan e these systems often require ustomized pro essors whi h are optimized for a spe i appli ation. How-ever, designing an appli ation spe i pro essor an be time- onsuming and ostly, and therefore the toolset used for pro essor design has an important role. TTA Codesign Environment (TCE) is a semi-automated toolset developed at the Tampere University of Te hnology for designing pro essors based on an easily us-tomizable Transport Triggered Ar hite ture (TTA) pro essor ar hite ture template. The toolset provides a omplete o-design tool hain from program sour e ode to synthesizable hardware design and program binaries. One of the most important tools in the tool hain is the ompiler. The ompiler is required to adapt to ustomized target ar hite tures and to utilize the available pro essor resour es as e iently as possible and still produ e programs with orre t behavior. The ompiler is therefore the most ompli ated and hallenging tool t
